DESCRIPTION
The 74VHC157 is an advanced high-speed
CMOS
fabricated with sub-micron silicon gate and
double-layer metal wiring C
It consists of four 2-input digital multiplexer with
common select and strobe inputs. It is a
non-inverting multiplexer. When the STROBE

input is held high selection of data is inhibited and
all the outputs become low. The SELECT
decoding determines whether the A or B inputs
get routed to their corresponding Y outputs.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface 5V to 3V. All inputs and outputs
are equipped with protection circuits against static
discharge, giving them 2KV ESD immunity and
transient excess voltage.
