SN74ABTH18502PMR TI Universal Bus Transceiver | 64-LQFP (10x10) | 3-State, 5V Tolerant

Product Overview

The SN74ABTH18502PMR from Texas Instruments is a 18-bit universal bus transceiver with 3-state outputs, designed for asynchronous communication between data buses. It operates from a 4.5V to 5.5V supply and features 5V-tolerant I/Os, making it suitable for mixed-voltage systems. Housed in a 64-pin LQFP (10x10 mm) package, it offers high drive capability (up to 64 mA) and low propagation delay (typical 4.5 ns). The device supports bidirectional data flow with direction control (DIR) and output enable (OE) pins, ideal for memory interfacing, backplane driving, and bus isolation in telecom and industrial applications.
