Multiplexer, 2 to 1 |
(1-MUX) |
Selects one of 2 input values.
I0–I1 | Input values |
S | Select |
O | Output |
If Select is 1, input I1 is sent to the output. If Select is 0, input I0 is sent to the output.
Values received on unselected inputs are stored until the input is selected.
The output sends whenever a value is received at the input or Select.
If an unconnected input is selected the output value remains unchanged.
