DESCRIPTION
The LVQ157 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.
PIN CONNECTION AND IEC LOGIC SYMBOLS
It has better speed performance at 3.3V than 5V
LSTTL family combined with the true CMOS low
power consumption.
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.
