SN74ABT543ANT TI Bus Transceiver | 24-PDIP | 8-Bit, Non-Inverting, 3-State

Product Overview

The SN74ABT543ANT is an advanced 8-bit registered transceiver from Texas Instruments, designed for bidirectional asynchronous communication between two data buses. Housed in a 24-pin PDIP package, this device features non-inverting outputs with 3-state capability, making it ideal for bus-oriented systems. It operates with a wide supply voltage range of 4.5V to 5.5V and offers high drive capability up to 64mA, ensuring robust signal integrity in noisy environments. The device incorporates D-type flip-flops for data storage, with separate latch enable and output enable controls for flexible bus management.
