74LVC3G14

Triple inverting Schmitt trigger with 5 V tolerant input

Rev. 03 — 31 January 2005

Product data sheet

1. General description

The 74LVC3G14 is a high-performance, low-power, low-voltage, Si-gate CMOS device

and superior to most advanced CMOS compatible TTL-families.

Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this

device as translator in a mixed 3.3 V and 5 V environment.

This device is fully specified for partial power-down applications using Ioff. The Ioff circuitry

disables the output, preventing the damaging backflow current through the device when it

is powered down.

The 74LVC3G14 provides three inverting buffers with Schmitt-trigger action. It is capable

of transforming slowly changing input signals into sharply defined, jitter-free output

signals.
