Combinational Logic: Multiplexers
Multiplexers
Examples: 74VHC157, 74VHC153
A multiplexer selects one signal from multiple input signals and forwards it to a single output line.
The following timing diagram shows how one signal is selected from two inputs.
When the SELECT pin is Low (0), a signal is forwarded from the A pin to the Y pin.
When the SELECT pin is High (1), a signal is forwarded from the B pin to the Y pin.
