74LVX14
Low Voltage Hex Inverter with Schmitt Trigger Input
General Description
The LVX14 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 LVX14 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 systems to 3V systems.
Features
s Input voltage level translation from 5V to 3V
s Ideal for low power/low noise 3.3V applications
s Guaranteed simultaneous switching noise level and
dynamic threshold performance

LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT
DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF FAIRCHILD
SEMICONDUCTOR CORPORATION. As used herein:
1. Life support devices or systems are devices or systems
which, (a) are intended for surgical implant into the
body, or (b) support or sustain life, and (c) whose failure
to perform when properly used in accordance with
instructions for use provided in the labeling, can be rea-
sonably expected to result in a significant injury to the
user.
2. A critical component in any component of a life support
device or system whose failure to perform can be rea-
sonably expected to cause the failure of the life support
device or system, or to affect its safety or effectiveness.
