FEATURES
GENERAL DESCRIPTION
The 74HC/HCT253 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.

The 74HC/HCT253 have two identical 4-input multiplexers
with 3-state outputs which select two bits from four sources
selected by common data select inputs (S
When the individual output enable (1OE, 2OE) inputs of
the 4-input multiplexers are HIGH, the outputs are forced
to the high impedance OFF-state. The “253” is the logic
implementation of a 2-pole, 4-position switch, where the
position of the switch is determined by the logic levels
applied to S
The logic equations for the outputs are:
1Y = 1OE(1l
2Y = 2OE(2l
