NOTES: (1) All values referred to V
and V
levels. (2) For bus line loads C
between 100pF and 400pF the timing parameters must be linearly interpolated.
(3) A device must internally provide a data hold time to bridge the undefined part between V
and V
IL
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.
