DESCRIPTION
The 74LVQ157 is a low voltage CMOS QUAD
2-CHANNEL MULTIPLEXER fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low power
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 inhibit and all
the outputs become low. The SELECT decoding
determines whether the A or B inputs get routed to
their corresponding Y outputs.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
