(1) Specified by design. Not tested in production.
(2) All values referred to VIHmin and VIHmax levels.
(3) For bus line loads CB between 100 and 400 pF, the timing parameters must be linearly interpolated.
(4) A device must internally provide a data hold time to bridge the undefined part between VIH and VIL of the falling edge of the SCLH signal. An input circuit with a threshold as low as possible for the falling edge of the SCLH signal minimizes this hold time.
