The 74ACT11257NG4 operates based on the principles of digital logic. It utilizes multiplexing techniques to select and route data from multiple inputs to specific outputs. The enable inputs (G1-G4) control the selection of data inputs (A0-A3, B0-B4), and the outputs (Y0-Y7) provide the selected data.
When an enable input is active (low), the corresponding data inputs are connected to the outputs. When an enable input is inactive (high), the outputs enter a high-impedance state, effectively disconnecting them from the data inputs.
The 74ACT11257NG4 finds applications in various digital electronic systems, including but not limited to:
