      Thanks a lot guys, i really appreciate your help.
      Actually I'm doing a Worst Case Analysis, that is why I need the figures as maximum as possible.
      But then, I need to support my analysis from such documents.
      I think everything is enough for now.
      Until next time.

      To quote the data sheet electrical specs,
      "TA = 40°C to 125°C, unless otherwise noted."

      This spec has no indication that it is not over the full temp range,
      so I would say 3% is the number to use. That should be good enough
      for async comms use if the other end is also within that spec. But
      this is pushing it to the max.
