DESCRIPTION
The 74LVT14 is a high-performance BiCMOS product designed for
V
CC
operation at 3.3V. They are capable of transforming slowly
changing input signals into sharply defined, jitter free output signals.
In addition, they have greater noise margin than conventional
inverters. Each circuit contains a Schmitt trigger followed by a
Darlington level shifter and a phase splitter driving a TTL totem-pole
output. The Schmitt trigger uses positive feedback to effectively
speed-up slow input transitions, and provide different input threshold
voltages for positive-going and negative-going input threshold
(typically 600mV) is determined internally by resistor ratios and is
insensitive to temperature and supply voltage variations.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
