NXP Semiconductors PCA9511A

The PCA9511A is a hot swappable I2C-bus and SMBus buffer that allows I/O card insertion into a live backplane without corrupting the data and clock buses. When the connection is made, the PCA9511A provides bidirectional buffering, keeping the backplane and card capacitances isolated. The PCA9511A rise time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise time requirements.
