description  
This quadruple 2-line to 1-line data selector/multiplexer is designed for 1.65-V to 3.6-V V  
operation.  
CC  
The SN74LVC157A features a common strobe (G) input. When the strobe is high, all outputs are low. When  
the strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The device  
provides true data.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators  
in a mixed 3.3-V/5-V system environment.  
The SN74LVC157A is characterized for operation from –40°C to 85°C.
