T
he 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 resi
stors to be connected betwee
n the SDA and the SCL pins and the SDA/SCL bus lines without
exceeding the maximum specified t
f
.
[6]
Input filters on the SDA and SCL inputs suppress noise spikes less than 50 ns.
Rise and fall times refer to V
IL
and V
IH
.
