+---+--+---+ A1 |1 +--+ 16| VCC B1 |2 15| Y C1 |3 14| S0 D1 |4 13| S1 A2 |5 12| GND B2 |6 11| B C2 |7 10| C D2 |8 9| D +----------+

Functional Features

• Dual 4-input multiplexer with common select inputs (S0 and S1).
• Each multiplexer has four data inputs (A1, B1, C1, D1) and one output (Y).
• The selection of input signals is determined by the state of the select inputs.
• When S0 and S1 are both low, the first multiplexer is selected, and its output is connected to Y.
• When S0 is low and S1 is high, the second multiplexer is selected, and its output is connected to Y.

Advantages and Disadvantages
