These parameters are characterized but not tested.
Note 1:
As a transmitter, the device must provide this internal minimum delay time to bridge the undefined region (min. 300 ns) of the fall-
ing edge of SCL to avoid unintended generation of START or STOP conditions.
2:
A fast-mode (400 kHz) I2C-bus device can be used in a standard-mode (100 kHz) I2C-bus 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 bus specification) before the SCL line is released.
Note:
Refer to Figure 13-4 for load conditions.
