Overview
The 74LVC1G332GW-Q100 is a single 3-input OR 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 range of supply voltages from 1.65 V to 5.5 V. It is particularly useful in mixed 3.3 V and 5 V environments due to its ability to accept inputs from both voltage levels.
The device features Schmitt-trigger action at all inputs, which enhances noise immunity and tolerance to slower input rise and fall times. Additionally, it includes IOFF circuitry, which prevents backflow current when the device is powered down, making it suitable for partial power-down applications.
This component is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), ensuring its reliability and performance in automotive applications.
