CD74HCT244E TI Buffer/Driver | 20-PDIP | 4.5V-5.5V, 8-Channel

Product Overview

The CD74HCT244E is a high-speed CMOS octal buffer and line driver designed by Texas Instruments. It features non-inverting outputs with three-state capability, making it ideal for driving bus lines or buffering memory address registers. Operating from a 4.5V to 5.5V supply, this device is compatible with TTL inputs and offers balanced propagation delays and high noise immunity. Packaged in a 20-pin PDIP, it is suitable for through-hole PCB assembly in industrial and automotive applications.
