8.2.4.1 Design Requirements

There are a few considerations when using these hot swap buffers. It is NOT recommended to place the TCA4307 on the backplane connector as it cannot isolate the cards from one another which will possibly result in disturbing on-going I2C transactions. Instead, place the TCA4307 on the I/O peripheral card to maximize benefit.
