SN74AS646DW TI Bus Transceiver | 24-SOIC | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74AS646DW from Texas Instruments is a high-performance octal bus transceiver and register designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and operates from a 4.5V to 5.5V supply. Housed in a 24-pin SOIC package, this device integrates D-type flip-flops for storage and control, enabling bidirectional data flow with direction control (DIR) and output enable (OE) pins. It is ideal for bus-oriented systems requiring high drive capability and low propagation delay.
