CD74HCT640M TI Bus Transceiver | 20-SOIC | 8-Bit, Non-Inverting, 3-State

Product Overview

The CD74HCT640M is a high-speed CMOS octal bus transceiver from Texas Instruments, designed for asynchronous two-way communication between data buses. It features non-inverting 3-state outputs and operates from a 4.5V to 5.5V supply. The device is fabricated with silicon gate technology to achieve propagation delays similar to LSTTL while consuming significantly lower power. Housed in a 20-pin SOIC package, it is ideal for driving bus lines or buffering memory address registers.
