CD74AC646M TI Bus Transceiver | 24-SOIC | 8-Bit, Non-Inverting, 3-State

Product Overview

The CD74AC646M from Texas Instruments is a high-speed octal bus transceiver and register designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and operates from 1.5V to 5.5V, making it suitable for mixed-voltage systems. The device integrates D-type flip-flops with independent input and output registers, allowing data flow in either direction. Packaged in a 24-pin SOIC, it is ideal for space-constrained applications.
