... Placing a bus buffer on the edge of each card, however, isolates the card capacitance from the backplane. For a given I/O card, the PCA9510A drives the capacitance of everything on the card and the backplane must drive only the capacitance of the bus buffer, which is less than 10 pF, the connector, trace, and all additional cards on the backplane. See Application Note AN10160, ‘ ...

... SDA SCL Remark: The PCA9510A can be used in any combination depending on the number of rise time accelerators that are needed by the system. Normally only one PCA9510A would be required per bus.
