3 Description

The SN74LV14B-EP device contains six independent

Inverter with Schmitt-trigger inputs designed for 2 V to

5.5 V VCC operation. Each gate performs the Boolean

function Y = A in positive logic.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables

the outputs, preventing damaging current backflow

through the devices when they are powered down.
