Hi Guys,

A few days ago I mentioned that I had a couple of mysterious IC's that I
had found in a box of semiconductors. Â*Attached are two photos of the
device "p1.jpg" showing the top and its markings. Â*The calibrated scale
at the top is 0.5mm divisions. Â*The second photo "p2.jpg" shows a shot
of the bottom of the device. Notice that it has four groups of three
gold plated leads. Â*I left it in its anti static foam, so the black
background is the A/S foam.

They are/were in anti static bags with a "Ferranti" label sealing the
bag. I don't think that the manufacturers logo is "Motorola" ! Â*I've
not found this one yet.

With a date code of 1986, I doubt there is a data sheet on the net anywhere.

Also, Ferranti in a military supplier !!

Where did you get these parts ???

If it were a Ferranti part, it could have been something like a
2-phase CMOS clock line driver, similiar to Nat Semi hybrid MH0009 or
MH0012. Ferranti was heavily into cmos.

The package was once a good fit for medium power hybrids,
instrumentation op amps, filters, oscillators, analog switches or even
SAW devices.

Don't recognize the logo, (it could even be Seiko, if it had an
underlining bar). Who's ever it was, I bet they changed it, if the
company hung around for any length of time.

They were part of an auction lot from a defunct company.

Wow ! I did a "datasheetarchive" search and got nothing !
You got magic fingers or something. :-)

*WAS* a military supplier. Now defunct.


And became "Zetex" ! It was almost destroyed by a corrupt takeover.
