Product Overview
The SN74LS244DWR is a high-performance octal buffer and line driver designed by Texas Instruments (TI) for 5V logic systems. It features eight non-inverting buffers with three-state outputs, organized as two 4-bit sections with independent output enable controls. Housed in a 20-pin SOIC package, this device is ideal for driving bus lines or buffering memory address registers. Its low-power Schottky (LS) technology ensures high speed and low power consumption, making it suitable for a wide range of industrial and commercial applications.
