74HC253; 74HCT253
Dual 4-input multiplexer; 3-state
Rev. 5 — 21 January 2015
Product data sheet
1. General description
The 74HC253; 74HCT253 are high-speed Si-gate CMOS devices and are pin compatible
with Low-power Schottky TTL (LSTTL).
The 74HC253; 74HCT253 provides a dual 4-input multiplexer with 3-state outputs which
selects 2 bits of data from up to four sources selected by common data select inputs (S0,
S1). The two 4-input multiplexer circuits have individual active LOW output enable inputs
(1OE, 2OE).
The 74HC253 and 74HCT253 are the logic implementation of a 2-pole, 4-position switch,
where the position of the switch is determined by the logic levels applied to S0 and S1.
The outputs are forced to a high-impedance OFF-state when nOE is HIGH.
The logic equations for the outputs are:
1Y = 1OE 1I0 S1 S0 + 1I1 S1 S0 + 1I2 S1 S0 + 1I3 S1 S0
2Y = 2OE 2I0 S1 S0 + 2I1 S1 S0 + 2I2 S1 S0 + 2I3 S1 S0
