SN74ALS1645ANS TI Bus Transceiver | 8-bit | 3-State, Bidirectional

Product Overview

The SN74ALS1645ANS is a high-performance 8-bit bidirectional bus transceiver from Texas Instruments, designed for asynchronous communication between two data buses. It features 3-state outputs and operates with a wide supply voltage range of 4.5V to 5.5V. The device is ideal for driving heavily loaded buses with its high drive capability of up to 48mA sink and 24mA source. Housed in a 20-pin SO package, it offers a compact solution for data flow control in digital systems.
