Overview
The SN74LVC2G14DCKT, produced by Texas Instruments, is a dual Schmitt-trigger inverter designed for a wide range of voltage operations from 1.65 V to 5.5 V. This device performs the Boolean function Y = A and functions as two independent inverters, but with the added benefit of Schmitt-trigger action, which provides different input threshold levels for positive-going (VT+) and negative-going (VT–) signals. The device is fully specified for partial-power-down applications using the Ioff feature, which disables the outputs to prevent damaging current backflow when the device is powered down.
