SN74ALS1244AN TI Buffer/Line Driver | 20-PDIP | 4.5V-5.5V, 24mA Output

Product Overview

The SN74ALS1244AN is a high-performance octal buffer and line driver designed by Texas Instruments (TI). It features three-state outputs and is organized as two 4-bit buffers with separate output-enable (OE) inputs. Operating from a single 5V supply, this device provides high drive capability (24mA sink/source) while maintaining low power consumption. Housed in a 20-pin PDIP package, it is ideal for bus-oriented applications requiring high noise immunity and fast propagation delays.
