74ABT652CMSAX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ABT652CMSAX is an octal registered bus transceiver belonging to the 74ABT logic family. It integrates eight D-type flip-flops with bidirectional data paths, allowing multiplexed transmission of real-time or stored data between two buses. The device operates within a supply voltage range of 4.5V to 5.5V and features three-state outputs for effective bus isolation. Packaged in a 24-pin SSOP format, it supports high-speed digital applications requiring reliable data latching and direction control.
