Difference between a normal invertor and a hex invertor?

    I'm writing a short introduction to how an hex invertor works, and
    wondered what the difference between a hex invertor and a invertor was,
    if any?
    There's lots of references to hex invertors, but I can't seem to see
    anything about an invertor, or is it just a shortened name?

    Thanks
    Ben

    A hex inverter just means there are six inverters in
    one package. See. for example:

    The hex inverter was first used in Salem to remove spells cast on
    students that didn't read the books before writing their reports.
     
  4. Maybe you have to read Harry Potter? Hex inverters are bewitched normal ones
    :)

    Real useful, Petrus. If you don't know, or don't want to give, a useful
    answer, why bother responding at all?

    An inverter is just that - ONE inverter. It's rather unusual to find
    such a beast these days, though, since multiple inverters are commonly
    used in any given circuit.

    A hex inverter is six (hence the "hex") inverters stuffed into one
    package, each one of them operating independent of the other five in the
    package, but all of them sharing common power and ground connections.

    Think of it as being about the same as buying "a beer" or "a six-pack of
    beer". Sort of a "convenience pack".

    And nobody mentioned that the other inverter in the O.P.'s question might
    be a DC to AC power inverter....tisk tisk.

    At least in my experience over the past five years or so, single gate ICs (the
    little SOT23-5 and smaller derivatives, e.g., 7CS04) are *more* common than
    finding a 74xx04 on a PCB... the single gate ICs are used where some really
    simply logic is needed, whereas anything that starts to require more than a
    couple ends up in a (C)PLD or FPGA.

    What I want to know is what is an "invertor". Is it a person who inverts,
    or uses an inverter?

    One type is a logic gate that provides the NOT function while the other
    takes low voltage DC
    as an input and produces high voltage AC as an output.

    No, those are both inverters to my knowledge.

    Looks like "invertor" is "the muscle which turns the feet inward". Perhaps
    hexapeds (if that's the correct way to put it; "six-legged") would have hex
    invertors, then.

    Hex inverters are bewitched normal ones
    I disagree with your position completely.
    A rousing round of Bait the Lazy Student is always appreciated.
    It's so much more amusing than simply saying
    "Pay attention in class and do your own homework".
