Overview
The SN74LVC1G14YEPR is a single Schmitt-trigger inverter produced by Texas Instruments. This device is designed to operate over a wide 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 feature provides hysteresis, which makes the device tolerant to slow or noisy input signals. The SN74LVC1G14YEPR is fully specified for partial-power-down applications, utilizing Ioff circuitry to disable outputs when the device is powered down, preventing damaging current backflow.
