Hi expert,

Do we have a d-type flip flop that consume even less power than SN74AUP1G79?

Thanks

No; AUP is the logic family with the lowest power consumption.

Thanks Clemens, do we know the typical Ivcc value of this part ?

Hi Han,

AUP family typically has 1uA static current consumption. See the below app note for more info:

I_CC is mostly leakage currents, and is strongly dependent on temperature. The datasheet guarantees < 0.5 µA at 25 °C, and with the worst case being 0.9 µA at 85 °C, I would expect the typical value at 25 °C to be < 0.1 µA.

If you care about these amounts of power, then you should do your own measurements at the highest expected temperature.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
