SN74ALS646ANT TI Bus Transceiver | 24-PDIP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ALS646ANT is a high-performance 8-bit bus transceiver and register from Texas Instruments, designed for bidirectional asynchronous communication between two data buses. Housed in a 24-pin PDIP package, this device integrates D-type flip-flops with 3-state outputs, enabling data flow in both directions with storage capability. It operates from a single 4.5V to 5.5V supply and features advanced low-power Schottky (ALS) technology for high speed and low power consumption. The SN74ALS646ANT is ideal for applications requiring data buffering, latching, and bidirectional bus interfacing in industrial, telecommunications, and computing systems.
