Overview
The SN74LVC2G14DCKRG4, produced by Texas Instruments, is a dual Schmitt-trigger inverter designed for operation over a wide voltage range of 1.65 V to 5.5 V. This device is part of the LVC (Low-Voltage CMOS) family and is packaged in a 6-pin SOT-SC70 (DCK) package. The SN74LVC2G14 features NanoFree™ package technology, which uses the die as the package, enhancing its compactness and efficiency. The device contains two independent inverters that perform the Boolean function Y = A, with Schmitt-trigger inputs that provide different input threshold levels for positive-going and negative-going signals.
