MC74VHC1G04 Single Inverter IC: Features, Applications & Specifications
The MC74VHC1G04 is a single high-speed CMOS inverter (NOT gate) from onsemi, built using Very High-Speed CMOS (VHC) technology. It offers fast switching speed, low power consumption, and wide voltage operation, making it ideal for digital logic, signal conditioning, clock buffering, and level conversion applications.
This compact logic IC is widely used in embedded systems, industrial electronics, consumer devices, and automotive-adjacent designs.
What is MC74VHC1G04?
The MC74VHC1G04 is a single-gate inverter that performs logical inversion—output is the complement of the input. Unlike traditional multi-gate logic ICs, this device integrates only one inverter in a small SOT-23 or SC-70 package, allowing flexible placement close to the signal source.
It is fully TTL-compatible at 5 V, while also supporting low-voltage operation.
