- Aug 16, 2006Thanks 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.Earl

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.
