3.3 V hex inverter Schmitt trigger

Product data sheet
1. General description
The 74LVT14 is a high-performance BiCMOS product designed for V_CC operation at 3.3 V.
It is capable of transforming slowly changing input signals into sharply defined, jitter free
output signals. In addition, it has a 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 inputs. The threshold differential (typically 600 mV)
is determined internally by resistor ratios and is insensitive to temperature and supply
voltage variations.
