Product details
Overview
HCPL0611R1 from Fairchild Semiconductor is a single-channel, high-speed logic gate optocoupler with 10 MBit/s data rate, strobable open-collector output, and 3750 VRMS isolation voltage. It features AlGaAs LED input coupled to a bipolar-process photodetector logic gate, operates from -40°C to +85°C, and is used in ground-loop-isolated digital interfaces such as industrial PLC I/O and isolated RS-485 transceiver enable control.
For engineers reviewing the HCPL0611R1 datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay (≤75 ns), common-mode transient immunity (10,000 V/µs at 1 kV), strobable enable functionality, and SO-8 package compatibility with LSTTL/CMOS level-shifting requirements.
Technical Context
The HCPL0611R1 integrates an AlGaAs LED emitter optically coupled to a high-speed bipolar logic gate detector with strobable enable input (pin 7) and open-collector output (pin 6). Its internal noise shield enables superior common-mode rejection, and the output stage supports wired-OR configuration via external pull-up.
It operates within 4.5–5.5 V supply range, requires no external pull-up on the enable input due to internal biasing, and mandates a 0.1 µF bypass capacitor between pins 8 (VCC) and 5 (GND) for stable high-speed switching performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 10 MBit/s - Enables high-speed serial communication in isolated UART, SPI, or digital control links. |
| Propagation Delay | ≤75 ns (TPLH/TPHL) - Ensures timing-critical synchronization in real-time industrial control loops. |
| Common-Mode Immunity | 10,000 V/µs at 1 kV - Maintains signal integrity in noisy motor drive or power supply environments. |
| Isolation Voltage | 3750 VRMS - Meets reinforced insulation requirements for industrial safety standards (IEC60747-5-2). |
| Output Type | Strobable open-collector - Allows dynamic output gating and wired-OR bus sharing with other logic devices. |

Pinout & Package
HCPL0611R1 uses an 8-pin Small Outline (SO-8) package with standard 1.27 mm pitch, 5.13 mm body width, and 6.19 mm length. Lead coplanarity is ≤0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED input anode - Connect to current-limited digital source (e.g., microcontroller GPIO with series resistor). |
| 2 | Cathode | LED input cathode - Ground reference for input current path. |
| 3 | No Connect | Internally unused - Must remain unconnected per datasheet. |
| 4 | No Connect | Internally unused - Must remain unconnected per datasheet. |
| 5 | GND | Detector ground - Return path for output and enable circuitry; tied to 0.1 µF bypass capacitor. |
| 6 | VO (Output) | Open-collector logic output - Requires external pull-up; sinks up to 13 mA at VOL ≤ 0.6 V. |
| 7 | VE (Enable) | Strobable enable input - Active-high; enables/disables output state; internal pull-up eliminates external resistor. |
| 8 | VCC | Detector supply - 4.5–5.5 V logic supply; bypassed to pin 5 with 0.1 µF capacitor. |
Key Features
| Feature | Design Value |
|---|---|

| LSTTL/CMOS Interface Ready | Input threshold ≤5 mA and output compatible with TTL/CMOS loads - eliminates level-shifter ICs in mixed-voltage systems. |
Applications
| Industrial PLC Digital I/O Isolation | Isolated RS-485 Transceiver Enable |
|---|---|
Use Scenario: Isolating digital input/output signals between PLC CPU and field-mounted sensors/actuators operating in electrically noisy factory environments. IC Role / Device Role / Timing Role: Signal-level galvanic isolator providing bidirectional logic-level translation with <75 ns latency and 10 kV/µs noise rejection. Use Value: Prevents ground loop-induced errors and protects controller-side circuitry from high-voltage transients on field wiring. |
Use Scenario: Controlling enable/disable state of isolated RS-485 transceivers in multi-drop industrial networks where master and slave nodes operate at different ground potentials. IC Role / Device Role / Timing Role: Strobable gate driver for transceiver DE/RE pins, ensuring precise timing alignment during bus arbitration. Use Value: Eliminates bus contention by synchronizing transceiver activation with master command edges, even under fast-switching EMI conditions. |
| Switching Power Supply Feedback | Computer Peripheral Interface Isolation |
Use Scenario: Transmitting PWM or fault signals across primary-secondary boundary in offline AC/DC converters with >3 kVRMS working voltage. IC Role / Device Role / Timing Role: High-speed feedback coupler delivering error amplifier output or overcurrent flag with minimal propagation delay skew. Use Value: Enables fast-loop response (<100 ns total delay) while meeting reinforced insulation requirements for Class II power supplies. |
Use Scenario: Isolating USB-to-serial bridge or parallel port handshaking lines between host PC and external test instrumentation. IC Role / Device Role / Timing Role: Logic-level isolator for control signals (e.g., DTR, RTS, BUSY) preserving timing integrity at up to 10 Mbps. Use Value: Prevents ground-bounce coupling and ESD damage to host-side USB controllers during hot-plug events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar logic gate optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HCPL0601R1 | Same SO-8 package and pinout; identical electrical specs except lower CMTI (5,000 V/µs vs. 10,000 V/µs at 1 kV). | Suitable for less noisy environments (e.g., lab equipment); not recommended for motor drive feedback. | Select HCPL0601R1 only when CMTI ≥10 kV/µs is not required and cost optimization is prioritized. |
| ACPL-M61T-000E | Higher CMTI (25 kV/µs), CMOS detector (lower ICC), but non-strobable output and different pinout (no VE pin). | Better for ultra-noisy environments but lacks enable control; requires PCB redesign for pin compatibility. | Choose ACPL-M61T-000E only if strobability is unnecessary and maximum noise immunity is mandatory. |
Compared with HCPL0611R1, HCPL0601R1 offers identical form-factor and interface simplicity at reduced noise immunity, while ACPL-M61T-000E provides superior CMTI but sacrifices strobable control and requires layout changes - making HCPL0611R1 optimal for applications needing both timing-gated isolation and robust industrial-grade transient rejection.

FAQ
What is the maximum data rate supported by HCPL0611R1?
The HCPL0611R1 supports a guaranteed data rate of 10 MBit/s across its full operating temperature range (-40°C to +85°C), verified by propagation delay specifications (TPLH/TPHL ≤75 ns) and pulse width distortion ≤35 ns under standard test conditions (RL = 350 Ω, CL = 15 pF).
Does HCPL0611R1 require an external pull-up resistor on the enable pin?
No, HCPL0611R1 does not require an external pull-up resistor on pin 7 (VE). The device incorporates an internal pull-up resistor on the enable input, allowing direct connection to logic-level control signals without additional components.
What is the purpose of the 0.1 µF capacitor specified for HCPL0611R1?
The 0.1 µF bypass capacitor must be placed between pins 8 (VCC) and 5 (GND) of HCPL0611R1 to suppress high-frequency supply noise and ensure stable operation during fast switching transitions. Ceramic or solid tantalum types with low ESL are recommended and must be mounted adjacent to the package pins.
How does HCPL0611R1 differ from HCPL0637 in terms of output architecture?
HCPL0611R1 uses a bipolar-process photodetector output stage, while HCPL0637 employs a CMOS-process detector for lower power consumption. This results in higher ICCCL (13 mA vs. 21 mA) for HCPL0611R1 but enables strobable enable functionality absent in dual-channel HCPL0637.
Is HCPL0611R1 certified for reinforced insulation per IEC60747-5-2?
Yes, HCPL0611R1 is IEC60747-5-2 approved (VDE option), as confirmed in the HCPL06XX datasheet Rev. 1.0.8. This certification applies specifically to HCPL0600, HCPL0601, and HCPL0611 variants and validates its suitability for reinforced insulation in industrial safety-critical designs.
