Overview
The 74LVC1G125GW-Q100125 is a single buffer/line driver with 3-state output, manufactured 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, serving as a translator between these voltage levels. The device features Schmitt-trigger action at all inputs, making it tolerant of slower input rise and fall times. Additionally, it is fully specified for partial power-down applications using IOFF circuitry, which prevents backflow current when the device is powered down.
