HCPL-902J-500E

The HCPL-902J-500E is a single‑channel high‑speed optocoupler (optical isolator) from Broadcom/Avago. It provides galvanic isolation between the input (LED) side and the output side, allowing safe interfacing of a low‑voltage logic/control domain with a high‑voltage or noisy power stage. The device typically combines a fast input LED with a high‑gain photoreceiver and an integrated output stage, yielding compatible logic levels for TTL/CMOS drives and fast propagation.
Key points:
- High‑speed operation suitable for digital or isolated feedback paths.
- Output is TTL/CMOS‑compatible; easy to interface with microcontrollers and logic ICs.
- Built‑in isolation between input and output to protect control electronics.
- Available in standard packages (e.g., 8‑pin DIP/SOIC variants) with various isolation ratings and performance grades.
Applications include isolated feedback in switch‑mode power supplies, motor drives, instrumentation, and automotive sensor interfaces. For exact electrical specs, pinout, and safety ratings, consult the HCPL‑902J‑500E datasheet.

Are you asking for cross-reference equivalents from other manufacturers that match the HCPL-902J-500E’s specs (isolation voltage, speed, CTR, input/output voltages)? If yes, please specify the required isolation voltage, speed (ps/isolated bandwidth), and acceptable tolerances, and I’ll provide direct cross-reference parts.

Here are the core features of HCPL-902J-500E (high-speed, optically isolated amplifier):
- Galvanic isolation between input and output to protect functions and reduce noise
- High-speed optocoupler amplifier with buffered output for fast response
- Integrated LED input and photodetector/amplifier stage
- Logic-compatible output (TTL/CMOS compatible) usable from common 3.3 V or 5 V supplies
- Wide operating temperature range suitable for industrial environments
- RoHS-compliant (lead-free) packaging; available in standard small-outline/DIP formats
- Suitable for isolated signal sensing, motor control, power-electronics feedback, and isolated measurement
Note: For exact electrical specifications (isolation voltage, propagation delay, CTR range, CMIT, supply voltage ranges, package variants), please refer to the official datasheet.

- Pin count: 8 pins (8-pin DIP/SO-8).
- Function: One-channel optically isolated amplifier (HCPL-902J-500E). It provides galvanic isolation (up to 5 kV rms) between input and output. Input side drives an LED; output side is powered from a separate supply (Vcc2/GND2) and provides an amplified/ buffered output voltage (Vout) proportional to the input.

Manufacturer: Broadcom Inc. (formerly Avago Technologies).
