AD7671 - Input and Output Capacitance and Short Circuit current

I am currently doing SI analysis on AD7671 Digital interface. I would like to know following parameters for my analysis. I could not find them in datasheet.


1. Input capacitance - Pin + Input Buffer capacitance

2. Output Capacitance - Pin + Driver output capacitance

3. Short circuit current for Digital pins.

Can you suggest a way to calculate short circuit current from available parameters in the datasheet?


Please provide above values for both Normal mode and Warp mode, if there are changes between these two modes.
