SEMICONDUCTOR TECHNICAL DATA  
The MC74LCX258 is a high performance, quad 2–input inverting  
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

performance. A V specification of 5.5V allows MC74LCX258 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 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.
