LTM4668A PGOOD input current

Good evening,

I have got a question about the PGOOD open drain inputs of the LTM4668A.
It says that those pins are pulled to GND when the output voltage leaves the aimed voltage window.
In this case there is a resistance of R_pgood 275 Ohm left(?).

I would like to put some failure-indicator LEDs torwards those pins. [Vin -> pre-Resistance -> LED -> PGOODx]
I can not find any information about the maximum voltage at those Pins and the maximum input current.

I would be happy about some more electrical information about those pins.
Thanks for your help in advance Slight smile
