MC74LCX14

Low Voltage CMOS

Hex Schmitt Inverter With 5

V-Tolerant Inputs

The MC74LCX14 is a high performance hex inverter with

Schmitt–Trigger inputs operating from a 2.3 to 3.6 V 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 5.5 V allows MC74LCX14

inputs to be safely driven from 5 V devices.

Pin configuration and function are the same as the MC74LCX04, but

the inputs have hysteresis and, with its Schmitt trigger function, the

LCX14 can be used as a line receiver which will receive slow input

signals.

•Designed for 2.3 V to 3.6 V VCC Operation

•5 V Tolerant Inputs – Interface Capability With 5 V TTL Logic

•LVTTL Compatible

•LVCMOS Compatible

•24 mA Balanced Output Sink and Source Capability

•Near Zero Static Supply Current (10 A) Substantially Reduces

System Power Requirements

•Latchup Performance Exceeds 500 mA

•Current Drive Capability is 24 mA at Source/Sink

•Pin and Function Compatible with Other Standard Logic Families

•ESD Performance: HBM > 2000 V; Machine Model > 100 V

•Chip Complexity: 41 Equivalent Gates
