DESCRIPTION
The 74LVX157 is a low voltage CMOS QUAD 2
CHANNEL MULTIPLEXER fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS technology. It is ideal for low
power, battery operated and low noise 3.3V
applications.
It consists of four 2-input digital multiplexers with
common select and strobe inputs. When 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
system. It combines high speed performance with
the true CMOS low power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
