Hi,

For a 1.65 supply buffer:

- Pulldown range will be -1.65 to 3.3 V.

- Pullup range from -1.65 to 3.3 also in case of the typical corner.

 

 

Both ranges will be swept with 0.05 V step if you want to get the maximum number of point allowed (Maximum accuracy).

So, I think the 3.25 V in the pull up that you are talking about came from ignoring the last step in the pull up sweep.
