I have a problem identifying an IC. It is 16 pin DIP.
It's in a really old 1988 model "doorbell" noise toy in an old Connex 3300. It sounds really cool. (my opinion only please spare me the lecture)
On top it says:
J1000
CDI 2209
8532 2CE
on bottom it says CD09
2C
PHIL
I cannot find a cross reference for this part or the original manufacturer to save my life. Any ideas? I have absolutely ZERO idea what it is. Op Amp? Quad comparator? some other name that could belong in a space-craft? I am clueless about this one. Is there some way to test it with my scope and figure out @#%$ it is?
thanks
