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.
b
SDA
SCL
= total capacitance of one bus line in pF.
