I hope this group is an appropriate place to post this. I am trying to
get a datasheet for the Mostek alam clock IC MK50253N, produced in the
mid '70s. Mostek seem to have gone out of business in the '80s, and a
couple of online datasheet archive sites list the device, but don't
have a datasheet. Does anyone out there have one they could copy or
scan for me please?

Our data book scanning project has 7 Mostek data books included in the
next update. I hope its the right one, I'll check the other books if
not:

I thought Mostek only did memory ICs not consumer stuff

I thought Mostek only did memory ICs not consumer stuff

Not sure, the 7 data books cover:

4 x Memory Data Books and Design Guides
2 x Industrial Products Data Books
1 x 3870/F8 Microcomputer Data Book

Fantastic - thanks for such a quick and positive response!

TTFN,

Did any of the Heathkit clocks use it? Manuals are available for them,
at at least you'll get the pinout. I still have my GC-1005 (MK5017
chip) from the early 1970s, and the seconds digit has been blinking
erratically for about the past 30 years.

Thanks for the thought. Our messages must have crossed - the chaps at
datasheetarchive.com came up trumps with the real thing. Yes, I think
I have a dry joint on mine somewhere, as it is a bit erratic.
