Overview
The 74HC1G66GW-Q100H, produced by Nexperia USA Inc., is a single-pole, single-throw analog switch. This component features two input/output terminals (nY and nZ) and a digital enable input (nE). When the enable input (nE) is LOW, the analog switch is turned off. The device includes clamp diodes, allowing the use of current limiting resistors to interface inputs to voltages in excess of VCC. This analog switch is part of Nexperia's extensive portfolio of logic and analog ICs, designed to meet various application needs across different industries.
