DESCRIPTION

The 74LVQ14 is a low voltage CMOS HEX

SCHMITT INVERTER fabricated with sub-micron

silicon gate and double-layer metal wiring C2MOS

technology. It is ideal for low power and low noise

3.3V applications.

The internal circuit is composed of 3 stages

including buffer output, which enables high noise

immunity and stable output.

Pin configuration and function are the same as

those of the 74LVQ04 but the 74LVQ14 has

hysteresis between the positive and negative

input threshold typically of 650mV.

This together with its schmitt trigger function

allows it to be used on line receivers with slow

rise/fall input signals.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
