MM74C157
Quad 2-Input Multiplexers
General Description
The MM74C157 multiplexers are monolithic complemen-
tary MOS (CMOS) integrated circuits constructed with N-
and P-channel enhancement transistors. They consist of
four 2-input multiplexers with common select and enable
inputs. When the enable input is at logical “0” the four out-
puts assume the values as selected from the inputs. When
the enable input is at logical “1”, the outputs assume logical
“0”. Select decoding is done internally resulting in a single
select input only.
