These data selectors/multiplexers contain full  
binary decoding to select one of eight data  
sources  
and  
feature  
strobe-controlled  
complementary outputs. The 3-state outputs can  
interface with and drive data lines of bus-  
organized systems. When the strobe (G) input is  
high, both outputs are in a high-impedance state  
in which both the upper and lower transistors of  
each totem-pole output are off, and the output  
neither drives nor loads the bus significantly.
