74HC253; 74HCT253  
Dual 4-input multiplexer; 3-state  
Rev. 4 — 12 December 2011  
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  
2. Features and benefits  
Non-inverting data path  
3-state outputs interface directly with system bus  
Complies with JEDEC standard no. 7A  
Common select inputs  
Separate output enable inputs  
Input levels:  
For 74HC253: CMOS level  
For 74HCT253: TTL level  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Multiple package options  
Specified from 40 C to +85 C and from 40 C to +125 C
