onsemi M74VHC1GT04DFT1G Single Inverter Gate: Datasheet, Application Circuit, and Specifications
The onsemi M74VHC1GT04DFT1G is a single inverter gate belonging to the advanced high-speed CMOS (VHC) logic family. This compact device integrates one inverter function, making it an essential component for signal inversion in a vast array of digital circuits. Housed in an ultra-small SC-70-5 / SOT-353 package, it is specifically engineered for space-constrained applications where board real estate is at a premium.
Key Specifications and Electrical Characteristics
This inverter gate operates over a broad voltage range from 2.0V to 5.5V, providing excellent compatibility with various logic levels, including 3.3V and 5.0V systems. It features high-speed performance with typical propagation delay times of just 3.9 ns at 5V, ensuring swift signal processing. A critical attribute is its low power consumption, a hallmark of CMOS technology, with a very low static power dissipation. The device is designed with robust ESD protection, exceeding 2 kV per Human Body Model (HBM), which enhances the reliability and durability of the end product. Furthermore, it offers a high output drive capability, sourcing/sinking up to 8 mA, allowing it to directly interface with other components like LEDs or slightly higher current loads.
Typical Application Circuit
The primary function of the inverter is to take an input logic signal and provide its complement at the output. A fundamental application circuit for the M74VHC1GT04DFT1G is straightforward. The input pin is connected to the source signal (e.g., a microcontroller GPIO pin), the output pin drives the load, and both the VCC (supply voltage) and GND (ground) pins are connected to the power rails, with a 0.1 µF decoupling capacitor placed close to the VCC pin to ensure stable operation and suppress noise. This simple configuration can be used for:
Signal Conditioning: Cleaning up noisy digital signals by reshaping their waveforms.
Level Shifting: Interfacing between devices with slightly different logic voltage thresholds.
Waveform Generation: Creating simple oscillators (e.g., a ring oscillator) when combined with resistors and capacitors.
Driving Small Loads: Such as an LED (with a current-limiting resistor).
