Overview
The SN74ACT244DWRE4 is an octal buffer and driver integrated circuit produced by Texas Instruments. It is designed to enhance the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device is organized as two 4-bit buffers and drivers with separate output-enable (OE) inputs, allowing for flexible control over the output states.
