SN74ALS642A-IN TI Bus Transceiver | 8-bit | Non-Inverting, 3-State

Product Overview

The SN74ALS642A-IN 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. The device operates from a single 5V supply and is characterized for operation from 0°C to 70°C. It is ideal for driving high-capacitance loads and is commonly used in memory interfaces, microprocessor systems, and industrial control applications.
