Overview
The SN74LVC1G14DBVTE4 is a single Schmitt-trigger inverter produced by Texas Instruments. This device is designed to operate 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 SN74LVC1G14 is fully specified for partial-power-down applications using Ioff circuitry, which disables the outputs when the device is powered down to prevent current backflow and potential damage.
