Quad 2-Channel Multiplexer  
The TC74AC157 is an advanced high speed CMOS QUAD  
2-CHANNEL MULTIPLEXER fabricated with silicon gate and  
double-layer metal wiring C2MOS technology.  
It achieves the high speed operation similar to equivalent  
Bipolar Schottky TTL while maintaining the CMOS low power  
dissipation.  
This device consist of four 2-input digital multiplexer with  
common select and strobe inputs.  
When the STROBE input is held “H” level, selection of data  
is inhibited and all the outputs become “L” level.  
The SELECT decoding determines whether the A or B inputs  
get routed to their corresponding Y outputs.

TC74AC157FT  
All inputs are equipped with protection circuits against static  
discharge or transient excess voltage.
