Low-Voltage CMOS Quad
2-Input Multiplexer
With 5V-Tolerant Inputs
(Inverting)
The MC74LCX158 is a high performance, quad 2–input inverting
multiplexer 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 MC74LCX158 inputs to be
safely driven from 5V devices.
Four bits of data from two sources can be selected using the Select
and Enable inputs. The four outputs present the selected data in the
inverted form. The MC74LCX158 can also be used as a function
generator. Current drive capability is 24mA at the outputs.
• Designed for 2.7 to 3.6V VCC Operation
• 5V Tolerant Inputs — Interface Capability With 5V TTL Logic
• LVTTL Compatible
• LVCMOS Compatible
• 24mA Balanced Output Sink and Source Capability
• Near Zero Static Supply Current (10µA) Substantially Reduces System
Power Requirements
• Latchup Performance Exceeds 500mA
• ESD Performance: Human Body Model >2000V; Machine Model >200V
