description/ordering information  
These data selectors/multiplexers contain inverters and drivers to supply full data selection to the four output  
gates. A separate strobe (G) input is provided. A 4-bit word is selected from one of two sources and is routed  
to the four outputs. The ’HC157 devices present true data.
