Overview
The 74AHC1G66GV,125 is a single-pole, single-throw (SPST) analog switch produced by Nexperia USA Inc. This component is part of the 74AHC and 74AHCT family of logic ICs and is designed for use in a variety of electronic applications. The device features two input/output terminals (nY and nZ) and a digital enable input (nE), allowing it to act as a switch or translator in mixed voltage environments. The analog switch is turned off when the enable input (nE) is LOW, and this input is overvoltage tolerant up to 5.5 V.
