HD74HC253
Dual 4-to-1-line Data Selectors/Multiplexers (with 3-state outputs)
Description
The large output drive and 3-state features of this device make it ideally suited for interfacing with bus
lines in bus organized systems. When the output control input is taken high, the multiplexer outputs are
sent into a high impedance state.
When the output control is held low, the associated multiplexer chooses the correct output channel for the
given input signals determined by the select A and B inputs.
Features
High Speed Operation: t
pd
(Data to Y) = 18 ns typ (C
L

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)
