... Control circuitry prevents the backplane from being connected to the card until a stop bit or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9512 provides bi-directional buffering, keeping the backplane and card capacitances isolated. ...

... The PCA9510 (rise time accelerator is permanently disabled) and the PCA9512 (rise time accelerator can be turned off) are a little different with the rise time accelerator turned off because the rise time accelerator will not pull the node up, but the same logic that turns on the accelerator turns the pull-down off ...

... Note from the figures that 5 V systems should have at least 47 pF capacitance on their buses and 3.3 V systems should have at least 22 pF capacitance for proper operation of the PCA9512. Although the device has been designed to be marginally stable with smaller capacitance loads, for 300 ...
