Broadcom 1 Channel Logic Gate Optocoupler 3.75kV DIP-8

The Broadcom 1 Channel Logic Gate Optocoupler 3.75kV DIP-8 is a single-channel, low current optically coupled logic gate device providing 3.75kV isolation to separate circuits safely.

Overview

The device integrates a GaAsP LED with a high gain photo-detector featuring a three-state output stage and a detector threshold with built-in hysteresis. Its design removes the need for an external pull-up resistor, allowing direct drive of data busses, which simplifies circuit design and reduces component count.

Key Features

• Built-in hysteresis that improves differential mode noise immunity and helps prevent output signal chatter
• Three-state output stage for direct drive of data busses
• Compatible with TTL, LSTTL, and CMOS logic families
• Low input current requirement of 1.6mA
• Wide VCC operating range
• Data rate supporting high-speed transmission up to 2.5 Mbaud

Applications

This optocoupler is well suited to isolating high-speed logic interfaces, buffering input and output lines, and implementing isolated line receivers. It is designed for systems operating in high-noise industrial or automotive environments where reliable signal isolation is required.
