DESCRIPTION/ORDERING INFORMATION  
These quadruple 2-line to 1-line data selectors/multiplexers are designed for 1.65-V to 3.6-V VCC operation.  
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.
