Single NAND gate for power-sensitive glue logic
The Texas Instruments SN74AUP1G00DCKT is a single 2-input NAND gate from the 74AUP ultra-low-power logic family. It operates from 0.8 V to 3.6 V and draws a maximum quiescent current of 500 nA, making it a fit for battery-powered, portable, and always-on circuits where every microamp counts. The SC-70-5 package keeps board area small, and the -40°C to 85°C range covers most industrial and outdoor telecom enclosures.
500 nA quiescent — what it means for a battery budget
The 500 nA maximum quiescent current is the headline spec. In a system that spends most of its time in a low-power idle state — a sensor node, a handheld controller, a remote I/O module — this gate adds negligible drain to the battery budget. The wide supply range (0.8 V to 3.6 V) lets it run directly from a single Li-ion cell or a 3.3 V rail without a regulator, and it can interface with both 1.8 V and 3.3 V logic domains without level translation.
6.5 ns propagation delay — timing margin check
At 3.3 V with a 30 pF load, the maximum propagation delay is 6.5 ns. That is fast enough for general-purpose glue logic, enable gating, and control signal conditioning in systems running at a few tens of megahertz. It is not a high-speed clock buffer — if your path needs sub-3 ns, look at the 74LVC or 74AHC families. The output drive is 4 mA source and sink, adequate for driving a single CMOS load or a short PCB trace.
SC-70-5 — rework and inspection notes
The SC-70-5 (SOT-353) package is 2.0 mm × 1.25 mm with a 0.65 mm pin pitch. It is small enough that hand-soldering is possible with a fine tip and magnification, but the part is light and can shift during reflow if the solder paste is over-applied. The part is surface-mount only — no through-hole variant exists.
Active lifecycle and compliance
It is ROHS3 compliant, so it meets the current EU and global restriction requirements. No AEC-Q automotive qualification is listed — this is an industrial-temperature-grade part, not for under-hood or chassis-domain automotive use.
