SN54ALS251 . . . FK PACKAGE  
(TOP VIEW)  
These data selectors/multiplexers contain full  
binary decoding to select one-of-eight data  
sources and feature controlled complementary  
3-state outputs.  
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 the  
high-impedance state), the low impedance of the  
signal-enabled output drives the bus line to a high  
or low logic level. Both outputs are controlled by  
the output-enable (OE) input. The outputs are  
disabled when OE is high.
