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

(1) This is not a supply pin. The
substrate is attached to this pad using
conductive die attach material. There is
no electrical or mechanical requirement
to solder this pad. However, if it is
soldered, the solder land should remain
floating or be connected to GND.
