ADVANCED COMMUNICATIONS & SENSING
(1) Assuming no load connected to outputs and inputs fixed to VCC1,2 or GND.
(2) All values referred to VIH
(3) A device must internally provide a hold time of at least 300ns for the SDA signal (referred to VIH

(4) The maximum t
(5) A Fast-mode I
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 t
= 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released.
