MM54C157/MM74C157 Quad 2-Input Multiplexers
MM54C157/MM74C157 Quad 2-Input Multiplexers
February 1988
General Description
These multiplexers are monolithic complementary 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 outputs 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.

Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
operation.
