74ACTQ652SCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ652SCX is an octal bus transceiver and register IC from the ACTQ Quiet Series, housed in a 24-lead SOIC package. It integrates D-type flip-flops for independent A and B bus data storage with multiplexed real-time and stored transmission capabilities. The device operates within a 4.5V to 5.5V supply range and supports -40°C to +85°C temperatures. Key electrical parameters include 24 mA output drive current, TTL-compatible inputs, and propagation delays ranging from 2.0 ns to 10.5 ns depending on the signal path.
