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

performance. A V specification of 5.5V allows MC74LCX257 inputs to be

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.
