CD74HCT245E TI Bus Transceiver | 20-PDIP | 8-Ch, Non-Inverting, 4.5V-5.5V

Product Overview

The CD74HCT245E 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 packaged in a 20-pin PDIP, making it suitable for through-hole PCB assembly. With its high noise immunity and low power consumption, it is ideal for interfacing between different logic families or driving heavily loaded buses.
