DESCRIPTION
The 74LVT14 is a high-performance BiCMOS product designed for
VCC 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.
