Datasheet for Signetic NE553?

Guest
Anyone have anything on this old IC - from 1976? I can't find it in my
regular Data books, IC Masters (oldest one I have is 1978), etc.

It appears to be an up/down counter of some sort, splitting the input
clock generated by a 555 into two pulses - one slightly delayed relative
to the other - used on a programming card for a test fixture
(Kursh-Kasch video test fixture) for an early video game - Demolition
Derby by Chicago Coin.

It is most definite that the part number is NE553 BA, I am not missing a
digit. It is a 16pin DIP device. Power/gnd pins are 5 & 12...

Markings are:

S7604
NE553
BA


Thanks!

There's no NE553 in the 1974 Signetics databook. I don't have a later

one.

I almost want to say it has something to do with servo motor control, but
I don't know why that comes to mind, and certainly don't know that it
applies to the 553.

Signetics did come out with the NE558, which was a quad timer, sort of
like 4 555's in a package (but since there weren't enough pins, it
couldn't do all that the 555 did). Make sure you aren't reading the
"8" for a "3". You should be able to find the pinouts for the 558, and
comparing it to the circuit might show a match.

Just a thought but one of the things you can precisely do with the NE558 is
generate delayed pulses relative to a trigger input, like a clock.

I think you are correct - the NE558 does sound (and based on the PDF,
looks) like the same item as what I have. Must be a bad imprint on the IC.

Thanks, it makes a lot more sense now!
