RLBK is the resistance of the inductor LBK.
If AVDD is switched off, I/O pins must not obstruct the SDA and SCL lines.
The maximum tf for the SDA and SCL bus lines (300ns) is longer than the specified maximum tof for the output stages (250ns). This allows series protection resistors (Rs) to be connected between the SDA/SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf.
Input filters on the SDA and SCL inputs suppress noise spikes of less than 50ns.
