Overview
The SN74LVC1G14DBVT is a single Schmitt-trigger inverter produced by Texas Instruments. This device operates within a voltage range of 1.65 V to 5.5 V and performs the Boolean function Y = A. It features Schmitt-trigger inputs, which provide hysteresis to make the device tolerant to slow or noisy input signals. The SN74LVC1G14DBVT is available in a SOT-23 (DBV) package with 5 pins and is fully specified for partial-power-down applications using Ioff circuitry, which prevents current backflow and potential damage when the device is powered down.
