SN74ALS645ADWR TI Bus Transceiver | 20-SOIC | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ALS645ADWR is a high-performance 8-bit bus transceiver from Texas Instruments, designed for bidirectional asynchronous communication between two data buses. It features non-inverting outputs with 3-state capability, allowing multiple outputs to share a common bus. The device is fabricated using advanced ALS (Advanced Low-Power Schottky) technology, offering a balance of speed and power consumption. Housed in a 20-pin SOIC package, it is suitable for a wide range of digital systems requiring reliable data transfer.
