Overview
The SN74LVC1G14YZTR 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 is designed to be used in a variety of applications where noise immunity and stable operation are crucial. The SN74LVC1G14 features Schmitt-trigger inputs, which provide hysteresis to make the device tolerant to slow or noisy input signals. Additionally, it supports partial-power-down mode through Ioff circuitry, which disables the outputs when the device is powered down to prevent current backflow and potential damage.
