HD74HC251
1 of 8 Data Selectors/Multiplexers (with 3-state outputs)
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 determines which data
input is routed to the Y and W outputs.
Features
High Speed Operation: t

High Output Current: Fanout of 10 LSTTL Loads
Wide Operating Voltage: V
CC
= 2 to 6 V
Low Input Current: 1 μA max
Low Quiescent Supply Current: I
CC
(static) = 4 μA max (Ta = 25°C)
