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 V_CCoperation 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
