Note 22: All values referenced to VIH_I2C(MIN) and VIL_I2C(MAX).
Note 23: A device must internally provide a hold time of at least 300ns for the SDA signal (referred to as the VIH_I2C(MIN) of the SCL
signal) to bridge the undefined region of the falling edge of SCL.
Note 24: The maximum tHD:DAT need only be met if the device does not stretch the low period (tLOW_I2C) of the SCL signal.
Note 25: A fast-mode I2C bus device can be used in a standard-mode I2C bus system, but the requirement tSU:DAT
≥ 250ns must
be met. This is automatically 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_I2C(MAX) + tSU:DAT = 1000 + 250
= 1250ns (according to the standard-mode I2C specification) before the SCL line is released.
Note 26: CB—Total capacitance of one bus line in pF.
