GND  
These data selectors/multiplexers contain  
inverters and drivers to supply full binary decoding  
data selection to the AND-OR gates. Separate  
output-control inputs are provided for each of the  
two 4-line sections.

(TOP VIEW)  
The 3-state outputs can interface with and drive  
data lines of bus-organized systems. With all but  
one of the common outputs disabled (at a  
high-impedance state), the low impedance of the  
single enabled output will drive the bus line to a  
high or low logic level. Each output has its own  
strobe (G) inputs. The output is disabled when its  
strobe is high.
