Are there different revisions of the IC out there since this parts inception? Going back to when National Semiconductor manufactured this part, has the part remain function, fit and form equivalent?
There have been revisions in the datasheet since that time (in particular referring to FB_GND0 and FB_GND1 pinout and I'd like to ensure that these are:
1) solely documentation changes
2) there have been no changes to the pinout and function of the IC
