The document discusses multiplexers, which are combinational circuits that have multiple input lines and a single output line. A multiplexer directs binary information from one of its input lines to the output line, based on the values of its selection lines. For example, a 2x1 multiplexer has two data inputs, one selection input, and one output. It connects either the first or second data input to the output depending on whether the selection input is a 0 or 1.

- 2. Multiplexer • A multiplexer is a combinational circuit that has 2n input lines and a single output line. • Simply, the multiplexer is a multi-input and single-output combinational circuit. • The binary information is received from the input lines and directed to the output line. • On the basis of the values of the selection lines, one of these data inputs will be connected to the output. • A multiplexer is also treated as Mux.

- 3. Multiplexer • In 2×1 multiplexer, there are only two inputs, i.e., A0 and A1, 1 selection line, i.e., S0 and single outputs, i.e., Y. • On the basis of the combination of inputs which are present at the selection line S0, one of these 2 inputs will be connected to the output.
