DESCRIPTION  
The 74F251A is a logic implementation of a single 8-position switch  
with the switch position controlled by the state of three Select (S0,  
S1, S2) inputs. True (Y) and complementary (Y) outputs are both  
provided. The output enable (OE) is active Low. When OE is High,  
both outputs are in High impedance state, allowing multiple output  
connections to a common bus without driving nor loading the bus  
significantly. All but one device must be in High impedance state to  
avoid high currents that would exceed the maximum ratings when  
the outputs of the 3-State devices are tied together. When the output  
of more than one device is tied together the user must ensure that  
there is no overlap in the active Low portion of the output enable  
voltages.
