HCPL-091J-000E

HCPL-091J-000E is a high-speed optocoupler with a transistor output that provides galvanic isolation between input and output. It uses an LED input and a photodetector on the output side to deliver a logic-level signal on the isolated side. Isolation rating is typically around 5 kV rms. The “-000E” suffix denotes RoHS-compliant (lead-free). It commonly comes in an 8-pin package (DIP/SOIC) and is used to isolate microcontrollers/FPGA logic from high-voltage or noisy circuits (motor drives, power supplies, medical equipment). The output side needs a pull-up to a logic supply (usually 3.3–5 V). CTR varies with input current and temperature; check the datasheet for exact curves. For complete specs, pinout, and safe operating area, refer to the HCPL-091J datasheet.

HCPL-091J-000E is a high-speed optocoupler with TTL-compatible output. Common cross-references (depending on CTR, speed, isolation) include:
- TI: 6N137, 6N139
- Vishay: ILD213/ILD230 series
- Everlight: EL817 (slower)
- Sharp: PC817 (legacy)
For an exact cross, compare datasheets and packaging, as “equivalent” can vary by vendor.

Here are the typical features of the HCPL-091J-000E:
- High-speed optically isolated amplifier with integrated output
- TTL/CMOS-compatible output for direct logic interfacing
- Reinforced input-to-output isolation for safety and EMI suppression
- High common-mode transient immunity for noisy environments
- Wide operating temperature range suitable for industrial use
- Small 8-pin package (DIP-8/SO-8) and RoHS-compliant (000E suffix)
- Low input current with good CTR and stable performance over temperature
- Suitable for 3.3 V and 5 V logic, versatile for mixed-voltage systems
- UL/CSA safety approvals typically supported (per datasheet)

HCPL-091J-000E is an 8-pin optocoupler (available in 8-pin DIP and SO-8 packages). Functionally the pins provide:
- LED input: Anode and Cathode (input side)
- Output/supply: VCC (supply), GND, and the logic output (VOUT)
- Remaining pins are package/no-connect or internal ties (NC) depending on the package variant
(For exact pin numbers and the detailed pin-to-pin diagram refer to the manufacturer's datasheet for HCPL-091J-000E.)

- Manufacturer: Broadcom Inc. (formerly Avago Technologies). The HCPL-091J-000E is an optocoupler from Avago/Broadcom.
- What kind of company: A multinational American semiconductor company that designs, develops, and manufactures a broad range of semiconductor devices and related software for communications, data centers, networking, and industrial applications.

- Isolated high-speed digital data links between microcontrollers/DSPs and high-voltage/noisy power electronics
- Digital I/O isolation for PLCs, motor drives, inverters, and other industrial automation equipment
- Isolated feedback and control paths in switch-mode power supplies and power-management circuits
- Instrumentation and measurement systems requiring galvanic isolation between sensors and processing electronics
- General galvanic isolation in environments with high voltage, EMI, or safety requirements
Note: HCPL-091J-000E is a high-speed optocoupler; use in any application needing fast, reliable isolation between logic and high-voltage domains.

The HCPL-091J-000E is supplied in an 8-pin plastic dual in-line package (PDIP-8 / DIP-8).
