CD74FCT543M TI Octal Registered Transceiver | 3-State | Non-Inverting, 8-Bit

Product Overview

The CD74FCT543M is a high-performance octal registered transceiver from Texas Instruments, designed for bidirectional asynchronous communication between two data buses. It features non-inverting 3-state outputs and operates from a single 5V supply. The device incorporates D-type flip-flops with enable and direction control, making it ideal for buffered data transfer in bus-oriented systems. With propagation delays as low as 6.5 ns and high drive capability (64 mA sink/32 mA source), it ensures reliable operation in high-speed digital systems.
