I think you mean ISO/DIN and IEEE (or ANSI), as IEEE is in fact american
institution. But as far as I know the major of differences are in couple
analog symbols, as Europe switch to "american" logic gates symbol and most
of the time do not use "de-morgan" versions. I do not know how deep
differences are in transistors because I do not have access to all
documentation of standards.
