Triple buffer/inverter for ultra-low-power logic
The NXP 74AUP3G0434DC125 is a triple buffer/inverter from the 74AUP series, designed for ultra-low-power and low-voltage logic applications. It operates from a supply voltage range of 0.8 V to 3.6 V, making it suitable for battery-powered and portable devices where power efficiency is critical. With three independent circuits — two inputs on one channel and one input on another — it provides flexible signal buffering or inversion in a single 8-pin package. The single-ended output type simplifies integration into standard logic chains.
Supply voltage and temperature range
The 0.8 V to 3.6 V supply range covers the full low-voltage logic spectrum, from near-threshold operation at 0.8 V up to standard 3.3 V I/O levels. This flexibility allows the part to interface directly with modern low-voltage microcontrollers and FPGAs without level shifting. Rated for -40°C to 125°C operating temperature, it handles industrial and automotive ambient conditions. The wide temperature grade means it can sit in an engine bay or on a rooftop sensor node without derating.
Package and footprint
Housed in an 8-VFSOP package (2.30 mm width, 0.091" body), the 74AUP3G0434DC125 is a surface-mount device with a fine-pitch footprint. The supplier device package is also listed as 8-VSSOP — these are the same physical outline, so the PCB land pattern is interchangeable. The small package suits dense PCB layouts, but hand-soldering is feasible with a fine-tip iron and steady hands — the 0.5 mm pitch leads are visible under a loupe. For rework, a hot-air station at 300°C with a small nozzle works cleanly.
Output drive and logic type
Each output can source or sink 4 mA, which is typical for the AUP family's low-power design. This drive strength is sufficient for driving CMOS logic inputs or low-current LEDs, but not for heavy loads like relays or motors. The part functions as a buffer or inverter — the description lists it as an inverter, but the logic type field says buffer/inverter, so it likely offers both functions depending on the pin configuration. No Schmitt trigger input means the switching threshold follows standard CMOS levels.
