0.8 V to 3.6 V supply — the defining range
The SN74AUP2G04DCKR from Texas Instruments is a dual inverter from the 74AUP ultra-low-power logic family. It operates across a supply range of 0.8 V to 3.6 V, making it one of the few standard logic gates that can run from a 0.8 V rail — relevant for battery-operated and energy-harvesting designs where the core voltage drops below 1 V. The two independent inverter channels each sink or source 4 mA, enough to drive a following logic input or a low-power LED indicator through a series resistor. Quiescent current maxes at 500 nA across the full temperature range, so it won't eat into a sleep-mode budget.
6.2 ns propagation delay — timing margin at 3.3 V
With a maximum propagation delay of 6.2 ns at 3.3 V and 30 pF load, this inverter keeps up with moderate-speed clock and data paths. In a 10 MHz system the 6.2 ns represents about 6% of a 100 ns period — comfortable margin for most glue-logic applications. At lower supply voltages the delay increases; the 0.8 V end of the range will see significantly longer propagation times, so timing closure should be verified at the actual operating point.
Package and footprint — SC-70-6
The part comes in a 6-pin SC-70-6 (SOT-363) package, a common small-outline footprint that fits into dense PCB layouts. It is surface-mount only, so hand-prototyping needs a fine-tip iron or hot-air station.
Lifecycle and compliance
The SN74AUP2G04DCKR is listed as Active with no end-of-life notification. It is ROHS3 compliant, so it meets current European and global restrictions on hazardous substances. The industrial temperature range of -40°C to 85°C covers most commercial, telecom, and factory-automation environments — no AEC-Q automotive grade on this variant, so it stays out of under-hood or chassis-domain designs that require the Q1 suffix.
Sourcing note
This is a current-production part from Texas Instruments, widely available through independent distribution. Pricing and stock levels are confirmed at quote time against an RFQ. For a BOM line that needs a dual inverter with sub-1 V capability and 500 nA quiescent draw, the 74AUP2G04 is a clean fit with no LTB risk.
