Dual unbuffered inverter for ultra-low-voltage logic
The Texas Instruments SN74AUC2GU04DCKR is a dual unbuffered inverter from the 74AUC series, designed for sub-3V logic rails down to 0.8 V. Each of the two independent inverters can sink or source 9 mA, and the propagation delay is 2 ns at 2.5 V with a 30 pF load. The part is housed in a 6-pin SC-70-6 (SOT-363) package for surface-mount assembly and operates over the industrial temperature range of -40°C to 85°C.
The 0.8 V to 2.7 V supply range places this part in the ultra-low-voltage logic tier. It is a fit for battery-powered handhelds, near-threshold computing blocks, or any design where the core logic rail is below 1.8 V. Quiescent current is a maximum of 10 µA across the full supply range, so the part adds negligible standby draw in always-on sensor interfaces or wake-up logic chains.
