Overview
The SN74LVC2G14DCK3 is a dual Schmitt-trigger inverter produced by Texas Instruments. This device is part of the SN74LVC2G14 family and is packaged in a SC70 (6-pin) package. It operates within a voltage range of 1.65 V to 5.5 V, making it versatile for various applications. The device performs the Boolean function Y = A and features Schmitt-trigger action, which provides different input threshold levels for positive-going and negative-going signals. This makes it ideal for handling slow or noisy inputs.
