SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX257 is a high performance, quad 2–input multiplexer  
with 3–state outputs operating from a 2.7 to 3.6V supply. High impedance  
TTL compatible inputs significantly reduce current loading to input drivers  
while TTL compatible outputs offer improved switching noise  
LOW–VOLTAGE CMOS  
QUAD 2–INPUT MULTIPLEXER  
performance. A V specification of 5.5V allows MC74LCX257 inputs to be  
I
safely driven from 5V devices.  
Four bits of data from two sources can be selected using the Select  
input. The four outputs present the selected data in the true  
(non–inverted) form. The outputs may be switched to a high impedance  
state by placing a logic HIGH on the Output Enable (OE) input. Current  
drive capability is 24mA at the outputs.
