If such a device does stretch the LOW period of the SCLH signal, it must output the next data bit to the SDAH line max_rise_time

A device must internally provide a hold time of at least 300 ns for SDAH signal in order to bridge the undefined region of the
falling edge of SCLH.
The maximum hold time has only to be met if the device does not stretch the LOW period (ID no IC6) of the SCLH signal
A Fast-mode I
of 250 ns must then be met. This automatically is the case if the device does not stretch the LOW period of the SCLH signal.
(ID No IC10) + data_setup_time (ID No IC8) = 1000 + 250 = 1250 ns (according to the Standard-mode I
before the SCLH line is released.
