Overview
The 74LVC1G04GW/C4125 is a single inverter integrated circuit produced by NXP USA Inc. This device is part of the LVC (Low Voltage CMOS) series and is designed to operate in mixed 3.3 V and 5 V environments. It features Schmitt-trigger action at all inputs, making it tolerant of slower input rise and fall times. The 74LVC1G04GW/C4125 is fully specified for partial power-down applications using IOFF circuitry, which prevents backflow current when the device is powered down.
