Overview
The SN74LVC1G14DRY2 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, making it versatile for various applications. It performs the Boolean function Y = A, acting as an independent inverter with Schmitt-trigger inputs. The Schmitt-trigger inputs provide hysteresis, which makes the device tolerant to slow or noisy input signals. The SN74LVC1G14DRY2 is available in several package types, including the 6-SON package, and is fully specified for partial-power-down applications using Ioff circuitry to prevent current backflow and device damage when powered down.
