DESCRIPTION
The M54/74HC157 and the M54/74HC158 are high
speed
CMOS
QUAD
PLEXER’s fabricated with silicongate C
2
MOStech-
nology. They achieve the high speed operation
similar to equivalent LSTTL while maintaining the
CMOS low powerdissipation.
These devices consist of four 2-input digital multi-
plexerswith common select and strobe inputs. The
HC158 is an inverting multiplexer while the HC157
is a non-inverting multiplexer. When the STROBE
input is held High, selection of data is inhibited and
all the outputs become Low in the M74HC157and
High in the M74HC158. The SELECT decoding
determines whether the A or B inputs get routed to
their corresponding Y outputs. All inputs are
equipped with protection circuits against static dis-
charge and transient excess voltage.
