I am using a BQ34Z651 gas gauge, and I have two communication paths. I would like to use two 9517A type buffers. I see warnings in the datasheet that the B side isn't compatible with other B sides, and I don't know what will connect out side of my battery (it just has to be SMbus compliant). I take this to mean that I have to have the A side connected externally, and the B side connected internally (to gas gauge).
The issue, is that I need to connect two buffers to the gas gauge. Only one buffer will be in use/ enabled at one time. And they do not have to talk to eachother. They will both be connected to the same Vcc however.
If the buffers are not enabled at the same time, can I connect two B sides to the gas gauge? or will one B side screw up the other even though it is disabled?
Thanks
