I need to have 2 separate IIC /TWI/I2C (or whatever you want to call it) networks, the Arduino will be a master on both. I really am looking for an inexpensive IC as I would prefer not to use the I2C software library.

TI makes the PCA9546A an I2C multiplexer so that an arduino can switch between two busses, if something like that would help.

Also the LTC4305, that will give you two channels. SMBus compatible as well if that helps.

These are two good ideas, the only concern I would have is missing data. or interrupts. Let me do some research around other chips in this category. Thank you all
