Schematic symbol of 2x1 mux. Let us assume logical area of a 2 1 mux to be a. Although it has four mux but we cannot control each mux individually.
This mux ic consists of quad 2 1 multiplexers within a single chip.
If s 3 is zero then the output of 2x1 multiplexer will be one of the 8 inputs is 7 to i 0 based on the values of selection lines s 2 s 1 s 0. The other selection line s 3 is applied to 2x1 multiplexer. 1 mux using transmission gate. The logic circuit and symbol of 2x1 mux is shown in figure 2.
