Overview
The SN74HC365NS is a hex buffer and line driver with 3-state outputs, manufactured by Texas Instruments. This integrated circuit is designed to enhance the performance and density of various digital systems, particularly in applications such as 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device contains six independent buffers/drivers with dual-gated output-enable (OE1 and OE2) inputs, allowing for flexible control over the output states.
