TLV1701: Can the pull-up attached to the open-drain output pin of the TLV1701 be pulled to a higher voltage than VS?

Part Number: TLV1701

If the TLV1701 is run from 5VDC supply, can the output be pulled up to 15V supply through a 10k resistor?

Of course, when the design is updated, the device will run from a 15V supply, but this is a rework of an existing design in which the compartor is powered by a 5V supply, but needs to drive the gate of a FET to 15V rather than 5V.

Thanks in advance,
Cody

    Hello Cody,

    Yes. You can pull the output up to 36V, independent of the comparator supply voltage.

    This is mentioned in the second paragraph of the front page description. Though I agree it is not well explained in the rest of the datasheet. I'll put that on the to-fix list for the next update.

    Hi Paul,

    No- you're right! That was 100% a case of the customer not thoroughly reading the front page of the data sheet before asking!  I just went straight to the AbsMax and ROC tables to look and assumed it wasn't covered. In my defense though, I probably wouldn't have trusted it only on the front page and would have asked you to verify anyway. :) 

    Thanks for the help!
