PCA9512 Level shifting hot swappable I2C and SMBus buffer

The PCA9512 is a hot swappable I2C and SMBus buffer that allows I/O card insertion into a live backplane without corruption of the data and clock buses and includes two dedicated supply voltage pins to provide level shifting between 3.3 V and 5 V systems while maintaining the best noise margin for e.

PCA9512 Features

* Bi-directional buffer for SDA and SCL lines increases fanout and

* Compatible with I2C standard mode, I2C fast mode, and SMBus standards to disable ∆V/∆t rise time accelerators through the ACC pin for lightly loaded systems prevents SDA and SCL corruption during live board inserti
