Overview
The SN74AC244PWLE is a dual 4-bit buffer and line driver integrated circuit produced by Texas Instruments. This component is part of the AC244 series, designed to enhance the performance and density of various digital systems. It operates within a voltage range of 2V to 6V, making it versatile for different application environments. The device is organized as two 4-bit buffers or drivers with separate output-enable (OE) inputs, allowing for non-inverted data transfer from the A inputs to the Y outputs when OE is low, and output disable when OE is high.
