    Hi Ao,

    The 1P1G125 (SN74LVC1G125-Q1) is a logic gate, not a power supply. What exactly are you trying to determine?

    Customers ask me for the dissipation power of this 1P1G125QDRYRQ1 and OPA2171AIDCUR. I think there is no relevant data, so asking questions for customers requires you to give an accurate standard reply to our customers.

    To help you with using E2E -- when you select a device for your post, it will automatically route the question to the appropriate applications team.

    Since you have two devices that are supported by two different teams, you should have two threads. I can help you with the 1P1G125QDRYRQ1 (which is the SN74LVC1G125-Q1), however another team will have to help with the OPA2171 device. I would recommend to create a second thread using that part number. Most likely, their answer will be very similar to mine -- you have provided almost no information to help calculate the power, so they will likely link you to a page or app note that explains how to do it.

    For CMOS logic devices like the SN74LVC1G125-Q1, power consumption is based on operating parameters -- it is not just a simple value that I can provide.

    The calculations required are shown in this FAQ: 

    [FAQ] How do I Calculate Power Consumption or Current Consumption for my CMOS Logic Device?

    Additionally, the customer may want to know about the maximum thermal dissipation - ie how much power can the device use without being damaged. This is also something they would need to calculate based on their usage of the device. We have an FAQ on this as well:
