Overview
The SN74LVC1G14-Q1 is a single Schmitt-trigger inverter designed by Texas Instruments. This device operates within a wide voltage range of 1.65 V to 5.5 V and is qualified for automotive applications, meeting the AEC-Q100 standards. It features a single inverter that performs the Boolean function Y = A, with the added benefit of Schmitt trigger action, which provides different input threshold levels for positive-going and negative-going signals. The device is fully specified for partial-power-down applications, utilizing Ioff circuitry to prevent damaging current backflow when powered down.
