If you're going to throw out a cryptic hint, at least provide a clickable link. If you had done so, and tested the link first as you should before posting, you would have found that the Wikipedia 471 entry describes a year in the Julian calendar. Not a great deal of help for an electronics novice. Most of us assume that you meant LM741 or uA741, which, if you search in Wikipedia, comes up with the Operational Amplifier entry.Just look at the 471 innards on Wikipedia.
