PCA9511A Hot swappable I2C-bus and SMBus bus buffer

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. Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without bus co.

PCA9511A Features

* s Bidirectional buffer for SDA and SCL lines increases fan out and prevents SDA and SCL corruption during live board insertion and removal from multi-point backplane systems s Compatible with I2C-bus standard mode, I2C-bus fast mode, and SMBus standards s Built-in ∆V/∆t rise time accelerators on all
