Multiplexer Logic Gate Diagram. Lastly outputs of all and gates became the input. Implantation of multiplexer using logic gates is given below.
A mux need and gates equal to the number of input channels not gates equal to the number of control signals and a single or gate. The symbol used in logic diagrams to identify a multiplexer is as follows. But only one has output line.
Multiplexer can act as universal combinational circuit.
We can implement the 16 1 multiplexer using a lower order multiplexer to implement the 8 1 multiplexer we need two 8 1 multiplexers and one 2 1 multiplexer the 8 1 multiplexer has 3 selection lines 4 inputs and 1 output the 2 1 multiplexer has only 1 selection line. Logical circuit of the above expression is given below. Mux is a device that has 2 n input lines. Schematic diagram of 2 to 1 multiplexer using logic gates.
