PCA9513A Hot swappable I2C-bus and SMBus bus buffer

The PCA9513A and PCA9514A are hot swappable I2C-bus and SMBus buffers that allow 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 wi.

PCA9513A Features

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