74LVT14
3.3 V hex inverter Schmitt trigger
Rev. 02 — 25 April 2008
Product data sheet
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
I Different positive and negative going input threshold voltages
I Tolerant of slow input transitions
I High noise immunity
I TTL input and output switching levels
I Output capability: +32 mA/20 mA
I Latch-up protection exceeds 500 mA per JESD78 class II level A
I ESD protection:
N HBM JESD22-A114E exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
