NXP Semiconductors PCA9510A

The PCA9510A 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 PCA9510A provides bidirectional buffering, keeping the backplane and card capacitances isolated. The PCA9510A has no rise time accelerator circuitry to prevent interference when there are multiple devices in the same system.
