74LCX14

Low Voltage Hex Inverter

with 5V Tolerant Schmitt Trigger Inputs

General Description

The LCX14 contains six inverter gates each with a Schmitt

trigger input. They are capable of transforming slowly

changing input signals into sharply defined, jitter-free out-

put signals. In addition, they have a greater noise margin

than conventional inverters.

The LCX14 has hysteresis between the positive-going and

negative-going input thresholds (typically 1.0V) which is

determined internally by transistor ratios and is essentially

insensitive to temperature and supply voltage variations.

The inputs tolerate voltages up to 7V allowing the interface

of 5V, 3V and 2.5V systems.

The 74LCX14 is fabricated with advanced CMOS technol-

ogy to achieve high speed operation while maintaining

CMOS low power dissipation.
