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.
