Overview
The SN74LVC2G14IDCKRQ1 is a dual Schmitt-trigger inverter produced by Texas Instruments. This device is designed to operate within 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 action. This action provides hysteresis, making the device highly tolerant to slow or noisy input signals. The SN74LVC2G14IDCKRQ1 is also qualified for automotive applications and supports partial-power-down modes using the Ioff circuitry, which prevents damaging current backflow when the device is powered down.
