Part Number: SN74AUP2G08
I am using multiple parts from the SN74AUP family to implement some logic that is powered from a battery source. I have included two SN74AUP2G08DCUR, two SN74AUP2G32DCUR, and one SN74AUP3G04DCUR in my design. I had expected the total current draw for the five devices to be less that 5uA since the datasheet indicated that the static-power consumption was 0.9uA maximum. The circuit does drive a single load that requires ~3.5uA of current, and with the implemented logic, I was expecting a total current draw for this circuit to be less that 10uA. Using a series resistor to measure the current, I am seeing ~35uA of current draw for this circuit. I have confirmed this current draw on two different implementations. I have also confirmed that the input signals are not transitioning. I have attached a copy of my schematic implementation. Can you provide additional support in idnetifying why I am observing a higher than expected current draw from these devices? Battery voltage is 3.61V. Is this VCC voltage the source of my extra current consumption? With a battery voltage of 3.54V, I still measure a current draw of 32.5uA.
I can provide a schematic for the E2E representative, but I would rather not post it publicly.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
