PCA9510
Hot swappable I2C-bus and SMBus bus buffer

Hot Swapping and Capacitance Buffering
Application
Figures 7 through 9 illustrate the usage of the PCA9510 and
PCA9511 in applications that take advantage of both its hot
swapping and capacitance buffering features. In all of these
applications, note that if the I/O cards were plugged directly into the
backplane, all of the backplane and card capacitances would add
directly together, making rise- and fall-time requirements difficult to
meet. 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 PCA9510 and PCA9511 drive 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

NOTE: The PCA9510 and PCA9511 can be used in any combination depending on the number of rise time accelerators that are needed by the
system. Normally only one PCA9511 would be required per bus.
