EL063X Series 8-Pin SOP Dual-Channel High-Speed 10Mbit/s Logic Gate Optocoupler Datasheet - Technical Documentation

1. Product Overview

The EL063X series is a class of dual-channel high-speed logic gate optocouplers (optical isolators). These devices are designed to provide robust electrical isolation and high-speed digital signal transmission between two circuits. Their core function is to transmit logic-level signals across an isolation barrier through optical coupling between an infrared light-emitting diode (LED) and a high-speed integrated photodetector with a logic gate output. This design effectively eliminates ground loops, prevents noise transmission, and protects sensitive circuits from voltage spikes or ground potential differences.

The primary application areas for this component include industrial automation, communication interfaces, power supply control, and computer peripherals, where reliable, noise-immune signal transmission is critical. The dual-channel configuration within a single package offers space-saving advantages for differential signal applications or multi-channel control line isolation and ensures consistency in channel characteristics.

2. Detailed Technical Parameters

Electrical and optical parameters define the operating boundaries and performance of the optical coupler.

2.1 Absolute Maximum Ratings

These are stress limits that must not be exceeded under any conditions, even momentarily. Operating beyond these ratings may cause permanent damage to the device.

• Input Forward Current (I_F)): 20 mA DC/average. This limits the maximum current through the input LED.
• Input reverse voltage (V_R)): 5 V. The maximum reverse bias voltage that the input LED can withstand.
• Output current (I_O)): 50 mA. The maximum current that the output transistor can sink.
• Output voltage (V_O) na voltage ya usambazaji (V_CC)): 7.0 V. Voltage ya juu inayoweza kutumiwa kwenye pini za upande wa pato.
• Voltage ya kutengwa (V_ISO)): 3750 V_RMS, kwa dakika 1. Hii ni kigezo muhimu cha usalama kinachoonyesha nguvu ya dielectri ya kizuizi cha kutengwa kati ya upande wa kuingiza na upande wa kutolea, wakati wa majaribio pini 1-4 zimeunganishwa pamoja, pini 5-8 zimeunganishwa pamoja.
• Halijoto ya kufanya kazi (T_OPR)): -40°C hadi +100°C. Anuwai ya halijoto ya mazingira ambayo inahakikisha kifaa kinafanya kazi kwa kawaida.
• Storage Temperature (T_STG)): -55°C to +125°C.

2.2 Electrical Characteristics

Vigezo hivi vinahakikishiwa chini ya hali maalum za uendeshaji (isipokuwa ikitajwa vinginevyo, Ta = -40°C hadi 85°C).

2.2.1 Sifa za Ingizo

• Forward voltage (V_F)): Typical value 1.4V, maximum 1.8V at I_F= 10 mA. Used to calculate the series resistor required for the input LED drive circuit.
• V_FTemperature coefficient: Approximately -1.8 mV/°C. The LED forward voltage decreases as temperature increases.
• Input capacitance (C_IN)): Typical value 60 pF. This parasitic capacitance affects the high-frequency performance on the input side.

2.2.2 Sifa na Tabia ya Usafirishaji

• Power supply current (I_CCH/I_CCL)): Outputs the static current consumed by IC. I_CCH(Output high level) Typical value is 13 mA (max 18 mA). At V_CCL= 5.5V, I_CC(Output low level) typical value is 15 mA (max 21 mA). This is important for power budget calculations.
• High-level output current (I_OH)): When the output maintains a high logic level (V_Oclose to V_CC), it can provide a maximum current of 100 µA. This is a relatively weak current sourcing capability.
• Low-level output voltage (V_OL)): katika I_F= 5mA na I_CL= 13mA, kiwango cha juu ni 0.6V. Hii inafafanua kiwango cha voltage wakati transistor ya pato inachukua mkondo kikamilifu, kuhakikisha kuwa inalingana na kizingiti cha chini cha mantiki ya TTL/CMOS.
• Kizingiti cha mkondo wa ingizo (I_FT)): Maximum 5 mA. This is the input current required to guarantee the output switches to the valid low-level state (V_O≤ 0.6V) under specified conditions. Designers must ensure the driving circuit provides at least this current to achieve reliable switching.

2.3 Tabia za Kubadili

These parameters define high-speed digital performance, measured under standard test conditions (Ta=25°C, V_CC=5V, I_F=7.5mA, C_L=15pF, R_L=350Ω).

• Propagation delay (t_PHL, t_PLH)): Kila moja hadi upeo wa 100 ns. t_PHLni ucheleweshaji kutoka kwenye pembejeo ya LED inayowashwa (mkondo unaopanda) hadi pato linaposhuka. t_PLHNi niukoleo kutoka kwa LED ya pembejeo kuzimika (mtoaji wa sasa kupungua) hadi pato kupanda. Niukoleo hizi hupunguza kiwango cha juu cha data.
• Uharibifu wa upana wa msukumo (|t_PHL– t_PLH|): Upeo wa 35 ns. Ukosefu wa ulinganifu huu kati ya viukoleo vya kupanda na kushuka hupotosha uwiano wa wakati wa msukumo unaotumwa, jambo muhimu katika matumizi yanayohitajika usahihi wa wakati.
• Output rise/fall time (t_r, t_f)): t_rTypical value is 40 ns (10% to 90%), t_fTypical value is 10 ns (90% to 10%). The faster fall time is characteristic of the active pull-down output stage.
• Common-Mode Transient Immunity (CMTI): This is a key parameter for noise immunity in noisy environments such as motor drives or switching power supplies. It measures the device's ability to suppress fast voltage transients appearing across the isolation barrier.
  • EL0630: Minimum 5000 V/µs.
  • EL0631: Minimum 10000 V/µs. The higher CMTI makes the EL0631 suitable for applications with more severe electrical noise.
  • This suppression capability applies to the output high level (CM_H) and the output low level (CM_L) Hali hali zote zimebainishwa, kuhakikisha pato halitafanya kosa kuanzisha wakati wa tukio la muda mfupi.

3. Performance Curve Analysis

Ingawa dondoo la PDF lililotolewa lilitaja "Mkunjo wa Kawaida wa Tabia ya Kielektroniki na Mwanga," chatifu maalum haijajumuishwa katika maandishi. Kwa kawaida, mikunjo kama hii ya kuunganisha mwanga inajumuisha:

• Current Transfer Ratio (CTR) versus Forward Current (I_F)Relationship: Shows the efficiency of optical coupling under different drive levels (output current / input current).
• Propagation Delay versus Forward Current (I_F)Relationship: Illustrates how switching speed varies with LED drive current. Higher I_Ftypically reduces propagation delay.
• Uhusiano wa Ucheleweshaji wa Usambazaji na Joto: Inaonyesha utegemezi wa joto wa kasi ya kubadili.Uhusiano wa Voltage ya Ujao wa Kujaa na Sasa ya Ujao: Inaonyesha utendaji wa transistor ya ujao inapokamata sasa.
• Wabunifu wanapaswa kukagua hati kamili ya data iliyo na michoro ili kuelewa uhusiano huu, na hivyo kuboresha matumizi yao maalum, kwa mfano, kufanya usawazishaji kati ya kasi na sasa/utumiaji wa nguvu wa LED.4. Mechanical and Package Information

Kifaa hiki kinatumia kifurushi cha kawaida cha pini 8 cha umbo dogo (SOP au SOIC). Kifurushi hiki cha kushikilia kwenye uso kinafanana na ukubwa wa kawaida wa kifurushi SO8, na hurahisisha upangaji wa PCB na usakinishaji.

4.1 Pin Configuration

Usanidi wa pini ni kama ifuatavyo:

Pini 1: Anodi (ingizo la LED ya kituo 1)

Pini 2: Kathodi (ingizo la LED ya kituo 1)

• Pin 3: Cathode (Channel 2 Input LED)
• Pin 4: Anode (Channel 2 Input LED)
• Pin 5: Ground (GND) - Output Side Common Terminal.
• Pin 6: V
• 2 (Channel 2 Output)
• Pin 7: V_OUT1 (Channel 1 Output)
• Pin 8: V_OUT(Output side power supply voltage, typical value +5V)
• Important Note:_CCInput and output sides are fully isolated. Pins 1-4 are on the isolated input side, and pins 5-8 are on the isolated output side. The PCB layout must maintain sufficient creepage distance and electrical clearance between the two sets of pins and their associated traces to maintain the isolation rating.

5. Mwongozo wa Uchimbaji na UsanikishajiKifaa hiki kinafaa kwa mchakato wa kawaida wa usakinishaji wa kufungia kwenye uso.

Joto la kuchomelea: Joto la juu linaloruhusiwa la kuchomelea ni 260°C, kwa sekunde 10. Hii inalingana na mkunjo wa joto wa kawaida wa kuchomelea bila risasi.

Uvumilivu wa unyevu: Ingawa haijaainishwa wazi katika dondoo, vifaa vingi vya SMD vilivyofungwa kwa plastiki vina kiwango cha usikivu wa unyevu (MSL). Ili kuzuia tukio la "popcorn" wakati wa kuchomelea tena, ni lazima kufuata miongozo ya mtengenezaji kwa usindikaji sahihi, kukaanga (ikiwa inahitajika), na uhifadhi.

• Output bypass: A critical design note (*3) specifies that VThe power supply pin (8) must be bypassed with a 0.1 µF or larger capacitor (ceramic or solid tantalum with good high-frequency characteristics). This capacitor must be placed as close as possible to pin 8 (V
• ) and pin 5 (GND) to ensure stable operation and minimize switching noise on the power rails.6. Mapendekezo ya Utumizi
• 6.1 Typical Application CircuitThe datasheet lists several key applications:_CCGround loop elimination: Primary function, isolating the grounds of two subsystems to prevent circulating currents and noise._CCLogic level conversion/interface: Can interface between different logic families (e.g., from LSTTL to TTL or 5V CMOS) while providing isolation.

Data transmission and line receivers: Suitable for isolated serial data links (e.g., RS-232, RS-485 isolation), digital I/O isolation, and multiplexing.

Switched-Mode Power Supply Feedback: In flyback or other isolated converter topologies, isolates the feedback signal from the secondary (output) side to the primary (controller) side.

Pulse Transformer Replacement: Provides a solid-state, potentially more reliable and compact alternative for transmitting digital pulses across an isolation barrier.

, na inaweza kuongezwa hadi kiwango cha juu kabisa cha ukadiriaji ili kuboresha kasi, lakini kwa gharama ya matumizi ya nguvu zaidi.

• Mzigo wa pato: Pato limeundwa kuendesha mizigo ya kawaida ya mantiki. Upinzani wa kuvuta juu R(connected between V_INand the output pin) sets the logic high level and rise time. A smaller R_Fprovides a faster rise time but increases power consumption when the output is low. Test conditions use R_F=350Ω._{Power consumption: Calculated on the input side (P}= V_IN* I_F) and the total power consumption on the output side, ensuring it remains within the specified limits, especially under high-temperature conditions._FChannel Selection: For applications requiring higher common-mode noise immunity (CMTI ≥ 10,000 V/µs compared to 5,000 V/µs), choose EL0631 over EL0630._F7. Technical Comparison and Differentiation_FTThe EL063X series stands out in the market through the following key features:
• High Speed: With a capability of 10 Mbit/s and a propagation delay of ≤100 ns, it belongs to the high-speed optocoupler category, suitable for fast digital communication.Ufungaji wa SOP-8 na njia mbili: Inajumuisha njia mbili za kutengwa kwenye ufungaji mwembamba wa kawaida, na kuokoa nafasi kwenye bodi ya mzunguko ikilinganishwa na vifaa viwili vya njia moja._LCMTI ya juu: Hasa CMTI ya chini ya 10 kV/µs ya EL0631 ina faida kubwa katika mazingira yenye kelele za umeme kama vile endesho la mota za viwandani, ambapo vichanganyishi vya mwanga vilivyo na CMTI ya chini vinaweza kushindwa._CCAnuwai pana ya joto: Inahakikisha utendakazi kutoka -40°C hadi 85°C, na anuwai ya uendeshaji hadi 100°C, inayofaa kwa matumizi ya viwandani na ya magari._LUthibitisho kamili wa usalama: Kifaa hiki kimeidhinishwa na mashirika makuu ya kimataifa ya usalama (UL, cUL, VDE, SEMKO, n.k.), ambayo kwa kawaida ni sharti la lazima kwa bidhaa za mwisho katika soko linalodhibitiwa._LUsalama wa Mazingira: Halina halojeni (Br/Cl zimewekewa mipaka), halina risasi, inakidhi viwango vya RoHS na REACH, inakidhi kanuni za kisasa za usalama wa mazingira.
• 8. Maswali Yanayoulizwa Mara kwa Mara (Kulingana na Vigezo vya Kiufundi)Swali: Kasi ya juu ya data inayoweza kufikiwa kwa kutumia kiunganishi hiki cha mwanga ni nini?_DJibu: Uainishaji wa 10 Mbit/s na ucheleweshaji wa juu wa uenezaji wa 100 ns unaonyesha kuwa, kwa data ya NRZ, kasi ya juu ya kinadharia ya data ni takriban 5-10 Mbps. Kwa vitendo, kasi inayoweza kufikiwa inategemea umbo maalum la wimbi, nyakati za kupanda/kushuka na upotovu wa upana wa msukumo. Kwa uendeshaji thabiti, lengo la kawaida la muundo wa makini ni 1-5 Mbps._FSwali: Ninawezaje kuchagua kati ya EL0630 na EL0631?_FA: Tofauti kuu iko katika kukandamiza msukumo wa kawaida (CMTI). Ikiwa matumizi yako yanahusisha kelele kubwa ya kubadili (mfano, karibu na kiendeshi cha motor, kigeuzi chenye nguvu kubwa, chanzo cha umeme chenye kelele), EL0631 (10 kV/µs) hutoa uwezo bora wa kukabiliana na kelele. Kwa mazingira yenye kelele chache, EL0630 (5 kV/µs) inaweza kutosha.
• Q: Kwa nini Vinahitaji capacitor ya bypass?

A: Kubadili kwa kasi kwa daraja la pato linaweza kusababisha V

line. The local bypass capacitor provides a low-impedance source for this current, preventing the V

• line from experiencing voltage droops or spikes, which could otherwise lead to operational instability or noise radiation. Placing it close to the pin is crucial for effectiveness.Swali: Naweza kutumia kifaa hiki kutenganisha ishara za analogi?
• Jibu: Hapana. Hii niKiungo cha mantiki
• Kifaa cha kuunganisha kwa mwanga. Pato ni kiwango cha mantiki ya dijiti (juu au chini), sio uwakilishi wa mstari wa mkondo wa pembejeo. Kwa kutenganisha analogi, inahitajika kutumia kifaa cha kuunganisha kwa mwanga cha mstari (kinacho na pato la fototransista au fotodiodi).Q: What is the purpose of the "triggerable output" mentioned in the description?
• A: Although not detailed in this excerpt, a triggerable output typically means the output stage has an enable or trigger control. This allows the output to be turned on/off or latched via a third control signal, which is useful in multiplexing applications or for reducing power consumption. The pin configuration here does not show a separate trigger pin, so this function may be internally integrated in a specific mode, or it may refer to the output being enabled by the input signal itself.9. Kanuni ya Uendeshaji
• The operating principle is based on photoelectric conversion. When sufficient forward current (I) is applied to the input infrared light-emitting diode (IRED), it emits photons. These photons pass through a transparent isolation barrier (typically a molded plastic compound). On the output side, a high-speed silicon photodetector integrated circuit receives this light. This IC contains a photodiode that converts the light back into a photocurrent. This photocurrent is then processed by internal amplifier and comparator circuits ("logic gates") to produce a clean, well-defined digital output voltage. When the input LED is on, the output is driven to a logic low state (typically via an active pull-down transistor). When the input LED is off, the output circuit pulls the pin to a logic high state (via an external pull-up resistor R
• ). This positive logic operation is summarized in the provided truth table as: input high = output low, input low = output high.10. Mwelekeo na Mazingira ya Sekta

The development of optocouplers such as the EL063X series is driven by several key trends in the electronics field:

Mahitaji ya kasi na upana wa bandi ya juu zaidi: Kadiri mitandao ya viwanda (EtherCAT, PROFINET IRT) na kasi ya interfaces ya mawasiliano inavyokua, vihifadhi lazima vifuate mwendo. Mwenendo wa kuanzia kilobiti hadi megabiti, na sasa kasi zaidi ya 10+ megabiti, unaonekana wazi.
Uwezo ulioimarishwa wa kukabiliana na kelele: Uchanganuzi wa umeme unaozidi kuwa tata katika mazingira ya viwanda na ya magari, unahitaji vihifadhi vilivyo na viwango vya juu vya CMTI, ili kuhakikisha utendakazi thabiti katikati ya kelele zinazotokana na madereva ya motor, vyanzo vya umeme vya kubadili-badili, na vyanzo vya redio.

Kupunguzwa kwa ukubwa na ushirikishaji: Ubunifu wa njia mbili katika kifurushi cha SOP-8 unaonyesha hitaji la kuokoa nafasi kwenye PCB na kupunguza idadi ya vipengele. Mienendo zaidi inajumuisha kushirikisha njia zaidi (vihifadhi vya njia nne) au kushirikisha uhitaji na utendaji mwingine (kama vile madereva wa ADC au I
C level shifting).

Higher Safety and Reliability Standards: Stricter safety regulations across industries are driving demand for components with higher isolation voltages, longer operational lifetimes, and robust certifications from bodies like UL, VDE, and CQC._CC?
Alternative Isolation Technologies: While optocoupler technology is mature, they face competition from capacitive isolators (using SiO_CCbarriers) and magnetic isolators (giant magnetoresistance or transformer-based), which may offer advantages in speed, power consumption, and integration density. However, optocouplers maintain a solid position due to their high CMTI, simplicity, and well-understood reliability._CCEL063X mfululizo unalenga kukidhi mahitaji ya soko ya upekee wa ishara yenye nguvu na utendaji wa juu, kwa kutumia usawa wa kasi, ujumuishaji wa njia mbili, CMTI ya juu na uthibitisho wa usalama.

Q: Je, naweza kutumia kifaa hiki kutenganisha ishara za analogi?
A: Hapana. Hiki nilogic gatephotocoupler. The output is a digital logic level (high or low), not a linear representation of the input current. For analog isolation, a linear optocoupler (with a phototransistor or photodiode output) is required.

Q: What is the purpose of the "strobable output" mentioned in the description?
A> While not detailed in this excerpt, a strobable output typically means the output stage has an enable or strobe control. This allows the output to be turned on/off or latched by a third control signal, which can be useful for multiplexing applications or reducing power consumption. The pin configuration here does not show a separate strobe pin, so this functionality may be integrated internally in a specific mode or may refer to the output being enabled by the input signal itself.

Kanuni ya Uendeshaji

Kanuni ya uendeshaji inategemea ubadilishaji wa optoelektroniki. Wakati mkondo wa mbele wa kutosha (I_F) unatumika kwa Infrared Emitting Diode (IRED) ya pembejeo, hutoa fotoni za mwanga. Fotoni hizi hupita kizuizi cha utengano kinachopitika mwanga (kwa kawaida kiwanja cha plastiki kilichotengenezwa). Upande wa pato, mzunguko wa jumuishi wa photodetector wa silikoni wa kasi ya juu hupokea mwanga huu. IC hii ina photodiode ambayo hubadilisha mwanga kurudi kuwa mkondo wa mwanga. Mkondo huu wa mwanga kisha huchakatwa na mzunguko wa kichocheo na kulinganisha wa ndani ("lango la mantiki") ili kutoa voltage ya pato ya dijiti safi na iliyofafanuliwa vizuri. Wakati LED ya pembejeo iko WASHI, pato huendeshwa hadi hali ya chini ya mantiki (kwa kawaida na transistor inayovuta chini). Wakati LED ya pembejeo iko ZIMA, mzunguko wa pato huvuta pini hadi hali ya juu ya mantiki (kupitia kipingamizi cha kuvuta nje R_L). Uendeshaji huu chanya wa mantiki umefupishwa kwenye Jedwali la Ukweli lililotolewa: Pembejeo Juu = Pato Chini, Pembejeo Chini = Pato Juu.

. Industry Trends & Context

Uundaji wa vichujio-vya-mwanga kama mfululizo wa EL063X unaendeshwa na mwenendo kadhaa muhimu katika uhandisi wa elektroniki:

• Mahitaji ya Kasi ya Juu na Upana wa Bendi: Kadri mitandao ya viwanda (EtherCAT, PROFINET IRT) na interfaces za mawasiliano zinavyokuwa na kasi, vipelelezi lazima viweze kuendana. Mwendo kutoka kilobiti hadi megabiti na sasa kuelekea kasi za zaidi ya megabiti 10 ni dhahiri.
• Ukinzani wa Kelele UliyoongezekaMazingira ya viwanda na ya magari yanazidi kuwa magumu zaidi kwa umeme, na kuhitaji vipelelezi vilivyo na viwango vya juu vya CMTI ili kuhakikisha utendakazi unaotegemewa katikati ya kelele kutoka kwa madereva ya motor, vifaa vya umeme vya kubadili, na vyanzo vya RF.
• Ufinyaji na UjumuishajiUsanidi wa njia mbili katika kifurushi cha SOP-8 unaonyesha hitaji la kuokoa nafasi kwenye bodi ya mzunguko na kupunguza idadi ya vipengele. Mienendo zaidi inajumuisha kuunganisha njia zaidi (vihifadhi vya pekee vya quad) au kuchanganya ufanyaji pekee na kazi zingine kama vile madereva wa ADC au I²C level translation.
• Viwango Vilivyoimarishwa vya Usalama na UaminifuKanuni kali za usalama katika viwanda vyote zinasisitiza vipengele vilivyo na voltage ya kutengwa ya juu, maisha marefu ya uendeshaji, na uthibitisho imara kutoka kwa mashirika kama vile UL, VDE, na CQC.
• Teknolojia Mbadala za KutengwaIngawa optocouplers zimekomaa, zinakabiliwa na ushindani kutoka kwa vitenganishi vya capacitive (vinavyotumia SiO₂Vizuwaa (kizuizi) na sumaku (upinzani mkubwa wa sumaku au kutengwa kwa msingi wa transfoma), ambazo zinaweza kutoa faida katika kasi, matumizi ya nguvu, na msongamano wa ujumuishaji. Hata hivyo, optocouplers zinaendelea kuwa na nafasi thabiti kutokana na CMTI yao ya juu, unyenyekevu, na uaminifu unaoeleweka vyema.

Mfululizo wa EL063X, kwa usawa wake wa kasi, ujumuishaji wa njia mbili, CMTI ya juu, na vyeti vya usalama, umewekwa ili kukabiliana na mahitaji haya yanayoendelea katika soko la kutengwa kwa ishara thabiti na yenye utendaji wa juu.
