OK, this is probably the world's dumbest sci.electronics question *but*:

How are the pins numbered on a 7404 ?  I know that 95% of the time they
are numbered, starting to the left of the notch, around the bottom
to the right of the notch.  However, I have now vaped three of these
chips (cheap, thankfully) on this assumption, and am beginning to believe
it might be wrong.  By the way, how fragile is a 7404 ?  Should I count
on replacing it later, due to surges and the like ?
Just putting it in backwards doesn't work, by the way, that's why I'm
asking about it's tolerance. :-)

Email answers, I don't think the whole world is interested.
