MULTIPLEXER
Logical MULTIPLEXER forwards the signal of
the inputs to the output according to the Sel
selection. If the SEL1÷SEL4 have only one
bit set, the selected In n is connected to the
Output. If the SEL inputs are:
- more than one = 1 (TRUE)
- none = 1 (TRUE)
the output is set to 0 (FALSE) independently
from the In n values.
Parameters
Number of inputs: this is used to set between 2 and 4 inputs.
