Thanks Paul and Gunther!
 

The chip i am wanting to address is the National LM4970, the more i look at the specs this chip has a address pin but the engineers at National says that it cannot be addressed as more than one chip. The address pin in the docs says it has 2 states X0 logic low and X1 logic high and is used to address a number of chips in a system, the LM4970's chip address can be changed to avoid any possible address conflicts. The way i take this is that the chip cannot be addressed as chip 1 thru 8 but can have all chips I2C lines tied together and the state of the address pins determine which chip can be addressed with I2C information!

 

I have included the link for the chip if someone would like to enlighten me as to how this works!
