http://www.farnell.com/nxp/ Two-wire I2C-bus multiplexers and switches provide capacitive isolation when connecting an upstream I2C-bus to a desired combination of downstream buses. The software-controlled multiplexers and switches break the I2C-bus into two sub-branches, four sub-branches, or eight sub-branches. The multiplexers allow only one downstream sub-branch to be selected at a time while the switches allow any individual downstream sub-branch or combination of downstream sub-branches to be selected.
