Overview
The SN74LVC2G14DCKRE4 is a dual Schmitt-trigger inverter produced by Texas Instruments. This device is designed for operation over a wide voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It features two independent inverters that perform the Boolean function Y = A, with the added benefit of Schmitt-trigger inputs. This design provides hysteresis, which makes the device tolerant to slow or noisy input signals. The SN74LVC2G14DCKRE4 is packaged in a SOT-SC70 (DCK) package with 6 pins, utilizing Texas Instruments' NanoFree™ package technology, which uses the die as the package.
