RE: Probably a stupid question...

I don't think I can 'borrow' any of the other gates :o( It's a bit busy
already at 1N! Plus it's two of the outputs that are incorrect. :o(

I thought I'd probably find an 'S' on my scrap Asteroids board, but that's
an LS version too (and a 7404 elsewhere). I'm going to try a friend of mine
tomorrow to see if he has one, else I think I'm just going to see how an LS
goes.

On other stuff. My 10.3v unregulated is running at over 12v! I know it's
unregulated, but that seems a bit too high to me? Is that normal?

Thank you :o)

A 74F04 is fast, a 74S04 is a schottkey, a 74LS04 is a low power schottkey .
a 7404 is just a plain old TTL. How many gates is the 74S04 driving?

Picked up a non-working Star Wars the other day, have already found a faulty
inverter at 1N but suspect there's more faulty parts to be found!

My question is this. can I replace the 74S04N at 1N with a 74LS04 or a
7404N? Normally I can find a matching part on my parts pile but I can't
find one of these anywhere! I'm suspecting the answer is no as I'm assuming
the S to mean it's fast (?)

Any help very much appreciated.

Thank you.
