Here you'll find a few DS2890:
https://www.m.nu/ds2890-p-354.html
I've had a hard time finding them...
m.nu is my webshop, and it is commercial. (Just to be clear). m.nu
certainly is not the cheapest place around, but that is not my goal
either. I doubt that any other store in the world has as wide range of
1wire products in stock as m.nu.
Regards
Erik

The datasheet for the DS2890 is on the maxim website:
http://datasheets.maximintegrated.com/en/ds/DS2890.pdf
but it doesn't seem to have the 8-pin package you show. Is it possible
that the pin numbers match the 6-pin TSOC, at least enough to test?
As for posting URLs (Erik Freiholtz's question), why not? Anything of
1-wire interest that isn't too obviously commercial is welcome. Even
commercial announcements of new products is fine if not repeated.

Hello to everyone!
I'm new to 1-Wire, worked only with ds18b20 for now.
Recently, I have bought some DS2890 to create some useful modules,
but surprisingly discovered, that there are no datasheets for these
chips in DIP8 package.
I bought them on alibaba site, they look quite factory-build. But I
have no idea how to use them. Have you ever worked with such?

Any advice would be appreciated!
