Note
1.
The bus capacitance ranges from 10 to 400 pF (C
b
= total capacitance of one bus line in pF).

C-BUS CHARACTERISTICS
All of the timing values are valid within the operating supply voltage and ambient temperature range and refer to V
IL
and
V
IH
with an input voltage swing from V
SS
to V
DD
.
Notes
1.
The hold time required (not greater than 300 ns) to bridge the undefined region of the falling edge of SCL must be
internally provided by a transmitter.
