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 'LVC257A devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in  
bus-organized systems. The 3-state outputs do not load the data lines when the output-enable (OE) input is at a  
high logic level.
