PCA9510 Hot swappable I2C and SMBus bus buffer

The PCA9510 and PCA9511 are hot swappable I2C and SMBus buffers that allows I/O card insertion into a live backplane without corrupting the data and clock buses. Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without.

PCA9510 Features

* Bi-directional buffer for SDA and SCL lines increases fanout and prevents SDA and SCL corruption during live board insertion and removal from multi-point backplane systems

* Compatible with I2C standard mode, I2C fast mode, and SMBus standards

* ∆V/∆t rise time accelerat
