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