Overview
The SN74LVC1G14MDBVREP is a single Schmitt-trigger inverter produced by Texas Instruments. This device is part of the LVC (Low-Voltage CMOS) family and is designed for operation over a wide voltage range of 1.65 V to 5.5 V. It features a single inverter that performs the Boolean function Y = A, with Schmitt-trigger inputs providing hysteresis to tolerate slow or noisy input signals. The device is available in various packages, including SOT-23, SC70, and others, and is fully specified for partial-power-down applications using Ioff circuitry to prevent current backflow when powered down.
