description  
These quadruple 2-line to 1-line data  
selectors/multiplexers are designed for 1.65-V to

operation.  
CC  
The ’LVC157A devices feature a common strobe  
(G) input. When G is high, all outputs are low.  
When G is low, a 4-bit word is selected from one  
of two sources and is routed to the four outputs.  
The devices provide true data.  
NC – No internal connection  
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 SN54LVC157A is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74LVC157A is characterized for operation from –40°C to 85°C.
