74HC253-Q100; 74HCT253-Q100

Dual 4-input multiplexer; 3-state

Rev. 2 — 21 January 2015

Product data sheet

1. General description

The 74HC253-Q100; 74HCT253-Q100 are high-speed Si-gate CMOS devices and are pin

compatible with Low-power Schottky TTL (LSTTL).

The 74HC253-Q100; 74HCT253-Q100 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-Q100 and 74HCT253-Q100 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

This product has been qualified to the Automotive Electronics Council (AEC) standard

Q100 (Grade 1) and is suitable for use in automotive applications.
