Working Principles

The CD74HC157M96E4 functions as a 2-input multiplexer/demultiplexer by utilizing CMOS logic. When the select inputs (A1 and A2) are set accordingly, the device routes the selected data input (B1 or B2) to the corresponding output (Y1 to Y7). The enable inputs (G1 and G2) control the operation of the multiplexer/demultiplexer. When both enable inputs are high, the outputs are in a high-impedance state.
