SN74LS244DBR TI Buffer/Driver | 20-SSOP | 8-Ch, Non-Inverting, 3-State

Product Overview

The SN74LS244DBR is a high-performance octal buffer and line driver designed by Texas Instruments (TI) to provide 8-bit non-inverting bus driving with 3-state outputs. Housed in a compact 20-pin SSOP package, this device is ideal for driving capacitive loads or low-impedance lines in digital systems. It features a typical propagation delay of 12 ns and a maximum output current of 24 mA, making it suitable for high-speed data transmission in industrial and telecommunications applications.
