74LVT14
3.3 V hex inverter Schmitt trigger
Rev. 3 — 6 April 2018
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 and benefits
• Different positive and negative going input threshold voltages
• Tolerant of slow input transitions
• High noise immunity
• TTL input and output switching levels
• Output capability: +32 mA/-20 mA
• Latch-up protection exceeds 500 mA per JESD78 class II level A
• ESD protection:
– HBM JESD22-A114E exceeds 2000 V
– MM JESD22-A115-A exceeds 200 V
