7tHD;DAT SDA Data Hold Time(2)
2.
tHD;DAT is the data hold time that is measured from the falling edge of SCL, applies to data in transmission and the acknowledge.
50(3)
3.
The device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge
the undefined region of the falling edge of SCL.
(4)
4.
The maximum tHD;DAT must be less than the maximum of tVD;DAT or tVD;ACK by a transition time. This device does not stretch the LOW period
(tLOW) of the SCL signal.

5.
A fast mode I2C device can be used in a standard mode I2C system, but the requirement tSU;DAT 250 ns must then be met. This will
automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of
the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the standard mode
I2C specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time.

tf
SDA and SCL Fall Time (3)(6)(7)(8)
7.
The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at
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 tf.
8.
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.
