These monolithic 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 ’HC158 present inverted  
data.
