# 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.

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.

11. ### Tim WilliamsGuest

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".
