SN74HCT244N TI Buffer/Line Driver | 20-PDIP | 8-Ch, Non-Inverting

Product Overview

The SN74HCT244N is a high-speed CMOS octal buffer and line driver designed for use as a memory and address driver, clock driver, and bus-oriented transmitter/receiver. It features eight non-inverting buffers with three-state outputs, providing the capability to drive highly capacitive or relatively low-impedance loads. The device operates from a 4.5 V to 5.5 V supply voltage and is compatible with TTL levels, making it ideal for interfacing with 5V logic families. Housed in a 20-pin PDIP package, the SN74HCT244N offers robust performance for industrial and commercial applications.
