Parameters are valid over operating temperature range unless otherwise specified.
t
A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the V
bridge the undefined region of the falling edge of SCL.
C
The maximum t
250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines
without exceeding the maximum specified t
In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should
allow for this when considering bus timing.
