Working Principles

SN74ALS153N consists of two independent 4-input multiplexers. The selection inputs (A0, A1, B0, B1) determine which inputs (I0-I3) are connected to the respective outputs (Y0-Y3). The enable inputs (E1, E2) control the output enable function for each multiplexer.

When the enable inputs are active, the selected inputs are routed to the corresponding outputs. When the enable inputs are inactive, the outputs are in a high-impedance state.

Detailed Application Field Plans

SN74ALS153N finds applications in various digital systems, including but not limited to: - Data multiplexing/demultiplexing in communication systems - Address decoding in microprocessors - Signal routing in test equipment - Data selection in industrial control systems
