概述

Description

HCPL-0631 is a high-speed optocoupler from Broadcom/Avago that provides electrical isolation between input and output for digital signals. It contains an infrared LED input and a photodetector with on-chip amplification and a TTL/CMOS-compatible output transistor. Typical isolation is around 5 kV rms. It is designed for faster performance than standard optocouplers and supports data rates in the Mbps range (varies by version) with fast propagation delay. The input LED requires a modest drive current (sense with a current-limiting resistor); the output side is powered separately (commonly 3.3 V or 5 V) and may use a pull-up if the output is open-collector. Applications include microcontroller I/O isolation, PLCs, industrial control, motor drives, and power-supply interfaces. The “#500” suffix is typically a batch/variant code for a specific lot or distributor—check the latest datasheet for exact CTR, propagation delay, CMR, and operating conditions for your part.

Features

Key features of HCPL-0631 (high‑speed optocoupler with logic output):
- 5 kV rms input–output isolation
- 25 kV/µs minimum common‑mode transient immunity
- TTL/CMOS‑compatible logic output (totem‑pole)
- Data rate up to 2.5 Mbps
- 8‑pin DIP or SO‑8 package (industrial variants available)
- Operating temperature range: -40°C to +85°C
- RoHS/compliant; suitable for isolated logic I/O to microprocessors
- Suitable for fast, reliable digital signal isolation in controllers and interfaces
(Applications: microprocessor I/O isolation, digital signal isolation, high‑speed gating with isolation.)

Package

An 8-pin DIP (through-hole) package.

Pinout

- Pin count: 8 pins (DIP package).
- Function: One-channel high-speed optocoupler with TTL/CMOS-compatible output; provides galvanic isolation between the input LED (input side) and the output logic (output side, which requires Vcc and GND). The #500 suffix indicates the specific package/reel variant.

Manufacturer
