PCA9510A Hot swappable I2C-bus and SMBus bus buffer

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. 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.

PCA9510A 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 Standard-mode I2C-bus, Fast-mode I2C-bus, and SMBus standards I Active HIGH ENABLE input I Active HIGH READY
