Ricky-
Can't speak from experience on this one, but the way I read the
datasheet it looks like this lets you "assign" an address to slaves
via jumpers, hook them all up to the same master, then select one of
up to eight via the control byte.

Steve

You can use up to 8 DS1621 on the same bus. Then you need to assign each
chip a different address (3 bits -> 8 combinations).

NEED to be tied low or high depending on what control code you use. I kept
getting 255 for a reading and I tied them all low and it works perfect now.
