Hi

Of course you can find the data sheet finding the part is the hard bit.

I can find it everywhere!

For example this:

http://mohodisco.com/monopoly/pdf/mm5837.pdf
http://www.chipdocs.com/pndecoder/datasheets/NSC/MM5837.html

Interesting noise generator page and meaurements including the mm5837.

http://www.ciphersbyritter.com/NOISE/NOISRC.HTM

and so on and on and on! :-)

BTW the MM5837 are also known as the "catchunka" generator!
It repeats its shiftregister noise at intervalls, a second or
so making it a hopeless cirquit, YET it has ben used in
synthesisers from the past such as P5,Source, Chroma!
