[sdiy] Mystery chips

[Mitchell Hudson]

    I'm going through my electronics junk box and I realize that I have
a bunch of chips that I don't recognize. Is there a site that shows the
standard part number?

    There are a bunch labeled 74HCT followed by various digits

74HCT688N
74HCT163
74HCT04N
74HCT00N
74HCT04
74HCT393

    The NTE chip, which I think was sent as a replacement for something
that I ordered that had a different number.

NTE992

    Then there are the even more mysterious ones

MN74C04
74SL93
741S93
CA3140
