SN74ALS641ANS TI Bus Transceiver | 20-SO | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ALS641ANS is a high-performance 8-bit bus transceiver from Texas Instruments, designed for bidirectional asynchronous communication between data buses. It features non-inverting outputs with 3-state capability, allowing multiple outputs to share a common bus. Housed in a 20-pin SOIC package, this device operates from a single 5V supply and is characterized for operation from 0°C to 70°C. The SN74ALS641ANS is part of the advanced low-power Schottky (ALS) family, offering a balance of speed and power consumption.
