Single 2-input NAND in the 74AUP family
The SN74AUP1G00DSF2 is a single 2-input NAND gate from Texas Instruments' 74AUP series — the ultra-low-power logic family that draws just 500 nA quiescent current maximum, making it a fit for battery-operated and always-on circuitry where every microamp counts. The 6-XFDFN package (1x1 mm body, 6-SON) keeps the footprint minimal — useful when board real estate is tight and the gate sits close to the load it drives.
What the 6.5 ns propagation delay means for timing
Maximum propagation delay is 6.5 ns at 3.3V with a 30 pF load — this sets the data-rate ceiling through the gate. At lower supply voltages the delay increases, so the usable toggle rate drops; at 1.2V the delay is roughly double the 3.3V figure. The 4 mA output drive at both high and low levels is enough to switch a downstream CMOS input or a short PCB trace, but not a long cable or a high-capacitance bus — plan a buffer if the fan-out exceeds a few gates.
