Overview
The 74LVC1G32GW-Q100125 is a single 2-input OR gate produced by NXP USA Inc., now part of Nexperia. This device is designed to operate in mixed 3.3 V and 5 V environments, making it an ideal choice for translation applications. It features Schmitt-trigger action at all inputs, which enhances noise immunity and tolerance to slower input rise and fall times. The device is fully specified for partial power-down applications using IOFF circuitry, preventing backflow current when powered down.
