1. General description
The 74LVT14 is a high-performance BiCMOS product designed for VCC 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.
2. Features
nDifferent positive and negative going input threshold voltages
nTolerant of slow input transitions
nHigh noise immunity
nTTL input and output switching levels
nOutput capability: +32 mA/20 mA
nLatch-up protection exceeds 500 mA per JESD78 class II level A
nESD protection:
uHBM JESD22-A114E exceeds 2000 V
uMM JESD22-A115-A exceeds 200 V
