I'm trying to find a substitute IC for the ancient "2524", 512-bit recirculating shift register (for use in a TV typewriter circuit). The datasheet can be found/downloaded here.
After some researching, it appears that this is simply an enormous "ring counter", but with only the last D flip-flop available for output (?). I've searched Digikey, Mouser, Jameco, using the search term of "ring counter" among many other types, but I can't find anything like the 2524! Is there another name for this that I'm missing? (I've tried "recirculating shift register", of course).
I would really appreciate if anyone could point me in the right direction!
Thanks,
