74ALVCH16543DL TI 16-bit Bus Transceiver | 56-SSOP | 3.3V, 5V Tolerant

Product Overview

The 74ALVCH16543DL from Texas Instruments is a 16-bit bus transceiver designed for asynchronous communication between data buses. It features two 8-bit transceivers with separate output-enable and direction controls, allowing bidirectional data flow. Operating from 2.3V to 3.6V, it is 5V tolerant on inputs and outputs, making it ideal for mixed-voltage systems. The device is housed in a 56-pin SSOP package, offering a compact solution for high-density board designs.
