MM54C157 MM74C157 Quad 2-Input Multiplexers
General Description
These multiplexers are monolithic complementary MOS
(CMOS) integrated circuits constructed with N- and P-chan-
nel 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'' Se-
lect 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
