t
A master device must internally provide a hold time of at least 300 ns for the SDA signal (refer to the V
bridge the undefined region of SCL’s falling edge.
The maximum t
250 ns. This allows series protection resistors to be connected between the SDA and the SCL pins and the SDA/SCL bus lines without
exceeding the maximum specified t
C
Input filters on the SDA and SCL inputs suppress noise spikes less than 50 ns.
