REQ: Old IC ID

[Alan 'A.J.' Franzman]

I found this IC the other day, and Google gets me nothing about it.

It's white ceramic with gold pins and wafer cover, 0.300" 14-pin DIP. There
is no maker name or logo on it.
Markings:
AD3737
7746L (probably date code + ?)

On the bottom it says "Hong Kong". It came from a digital readout
subassembly. That's all I can think to tell!

TIA

Probably analog devices, my old IC-Master shows nothing though so probably very old.
7746 would indicate week 46 of 1977

AD = Analog Devices? I remember that the CMOS A series came in those
ceramic packages, and were very ESD sensitive.

On the bottom it says "Hong Kong". It came from a digital readout
subassembly. That's all I can think to tell!

My advice may be worth what you paid for it.

Yes, I saw that page in my Google search but it tells nothing about *WHAT* it
is, which is my question.

So far all I've gotten on this request is that it was most likely made by
Analog Devices.

Can't anyone tell me what it is, pinout, etc.?
