Description

This dual Schmitt-trigger inverter is designed for
1.65-V to 5.5-V VCC operation.

NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.

The SN74LVC2G14 device contains two inverters and performs the Boolean function Y = A. The device functions as two independent inverters, but because of Schmitt action, it may have different input threshold levels for positive-going (VT+) and negative-going (VT–) signals.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
