Overview
The 74HCT1G66GW-Q100125 is a single-pole, single-throw (SPST) analog switch produced by NXP USA Inc. This component is part of the 74HC and 74HCT series, which are known for their compatibility with a wide range of logic levels and their suitability for various applications, including automotive systems. The device features two input/output terminals (nY and nZ) and a digital enable input (nE), allowing for precise control over the switching operation. When the enable input (nE) is LOW, the analog switch is turned off, and when it is HIGH, the switch is turned on.
