What this part is — triple unbuffered inverter from the 74AHC family
The 74AHC3GU04DC-Q100125 is a triple unbuffered inverter from Nexperia's 74AHC series. It contains three independent inverter gates, each with a single input, in a surface-mount package measuring 2.30 mm wide. The unbuffered output stage means the propagation delay and output drive are lower than a standard buffered gate, which can be an advantage in oscillator or linear-mode circuits where you want the gate to operate in its linear region. The part is qualified to AEC-Q100, making it suitable for automotive and industrial environments where the -40°C to 125°C temperature range is required.
Lifecycle and sourcing — active, no LTB risk
The 74AHC3GU04DC-Q100125 is listed as Active with no end-of-life notice. For a BOM line, this part carries no last-time-buy risk in the near term. The Q100 suffix confirms AEC-Q100 qualification, which also means the part has been through extended reliability testing (high-temperature operating life, temperature cycling, etc.) — a useful signal even for non-automotive designs that want a proven part.
