Overview
The SN74LVC1G14DRLRG4, produced by Texas Instruments, is a single Schmitt-trigger inverter integrated circuit. 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 highly tolerant of slow or noisy input signals due to its Schmitt-trigger inputs, which provide hysteresis. The SN74LVC1G14 is fully specified for partial-power-down applications, featuring Ioff circuitry that disables the outputs when the device is powered down, preventing current backflow and potential damage.
