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 VI 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. Designed for 2.7 to 3.6V VCC Operation 5V T olerant — Interface Capability With 5V TTL Logic Supports Live Insertion and Withdrawal IOFF Specification Guarantees High Impedance When VCC = 0V LVTTL Compatible LVCMOS Compatible 24mA Balanced Output Sink and Source Capability Near Zero Static Supply Current in All Three Logic States (10μA)
Substantially Reduces System Power Requirements Latchup Performance Exceeds 500mA ESD Performance: Human Body Model >2000V; Machine Model >200V
