For standard-mode I
C bus devices, the values of
resistors R
and R
in Figure 9-27 depend on the fol-

lowing parameters:
• Supply voltage
• Bus capacitance
• Number of connected devices
(input current + leakage current)
The supply voltage limits the minimum value of resistor
R
, due to the specified minimum sink current of 3 mA at

max = 0.4V, for the specified output stages. For

The bus capacitance is the total capacitance of wire,
connections, and pins. This capacitance limits the max-
