Working Principles

The DM74ALS253M is a dual 4-input multiplexer that combines four input signals into two output signals based on the control inputs G1 and G2. When G1 and G2 are both low, the outputs B0 and B1 follow the inputs A0-A3. When G1 is high and G2 is low, the outputs B0 and B1 follow the inputs A0-A3 inverted. Conversely, when G1 is low and G2 is high, the outputs B0 and B1 follow the inputs A0-A3 inverted. Finally, when both G1 and G2 are high, the outputs B0 and B1 are in a high-impedance state.
