MC74VHC157  
Quad 2-Channel Multiplexer  
The MC74VHC157 is an advanced highspeed CMOS quad  
2channel multiplexer, fabricated with silicon gate CMOS  
technology. It achieves highspeed operation similar to equivalent  
BipolarSchottky TTL, while maintaining CMOS lowpower  
dissipation.  
It consists of four 2input digital multiplexers with common select  
(S) and enable (E) inputs. When E is held High, selection of data is  
inhibited and all the outputs go Low.  
The select decoding determines whether the A or B inputs get routed  
to the corresponding Y outputs.  
The internal circuit is composed of three stages, including a buffer  
output which provides high noise immunity and stable output. The  
inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems  
to 3 V systems.
