Hot Swapping and Capacitance Buffering
Application
Figures 9 through 12 illustrate the usage of the PCA9513 and
PCA9514 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 PCA9513 or PCA9514 drives the capacitance of
everything on the card and the backplane must drive only the 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, Hot Swap Bus Bufferfor more
information on applications and technical assistance.
