t
VD;DAT
= minimum time for SDA data out to be valid following SCL LOW.
Minimum SCL clock frequency is limited by the bus time-out feature, which resets the serial bus interface if either SDA or SCL is held
LOW for a minimum of 25 ms. Disable bus time-out feature for DC operation.
[3]
[4]
A master device must internally provide a hold time of at least 300 ns for the SDA signal (refer to the V
IL
of the SCL signal) in order to
bridge the undefined region of SCLs falling edge.
[5]
C
b
= total capacitance of one bus line in pF.
The maximum t
f
for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage t
f
is specified at
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
f
.
Input filters on the SDA and SCL inputs suppress noise spikes less than 50 ns.
