Overview
The 74LVC1G02GW-Q100 is a single 2-input NOR gate produced by NXP USA Inc. This device is part of the LVC (Low Voltage CMOS) family and is designed to operate in a wide supply voltage range from 1.65 V to 5.5 V. It is particularly useful in mixed 3.3 V and 5 V environments, serving as a translator between these voltage levels. The device features Schmitt-trigger action at all inputs, enhancing its tolerance to slower input rise and fall times and providing high noise immunity.
