(1) RLBK is resistance of inductor LBK
(2) If AVDD is switched off, I/O pins must not obstruct the SDA and SCL lines.
(3) The maximum tf for the SDA and SCL bus lines (300 ns) is longer than the specified maximum tof for the output stages (250 ns). 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.
(4) Input filters on the SDA and SCL inputs suppress noise spikes of less than 50 ns
