HD74HC251  
1 of 8 Data Selectors/Multiplexers (with 3-state outputs)  
REJ03D0599–0200  
(Previous ADE-205-476)  
Rev.2.00  
Jan 31, 2006  
Description  
This multiplexer features both true (Y) and complement (W) outputs as well as a strobe input. The strobe must be at a  
low logic level to enable this device. When the strobe input is high, both outputs are in the high impedance state.  
When enabled, address information on the data select inputs determine which data input is routed to the Y and W  
outputs.  
Features  
High Speed Operation: tpd (A, B, C to Y) = 20 ns typ (CL = 50 pF)  
High Output Current: Fanout of 10 LSTTL Loads  
Wide Operating Voltage: VCC = 2 to 6 V  
Low Input Current: 1 µA max  
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
