MULTIPLEXER:
It select one of the input, it route to the output is known as
data selector.
There are 2*n input lines and n selection lines whose bit
combination determine which input line is selected.
Multiplexer is many to
one (many input but one output).
2:1
MULTIPLEXER:
D0 is applied as an input to one AND gate and D1 is applied as
an input to another AND gate.
Enable input is applied to both the gate.
An inverted S is applied to second input to first AND gate.
Selection line S is connected tas second input to second AND
gate.
Output of both the AND gates are connected as input to the OR
gate.

Application of MULTIPLEXER:
They can be used to implement combinational logic
circuit.
They are use in time multiplexing system.
They are used in frequency multiplexing system.
They are used in A/D or D/A converters.
They are
used in data acquisition system.
