To ensure proper voltage levels, the pullup resistor value is selected by ensuring that the pullup voltage divided by the resistor does not exceed the sink-current capability of the device. This confirmation is calculated by verifying that the pullup voltage minus the output-leakage current (Ilkg(OD)) multiplied by the resistor is greater the desired logic-high voltage. These values are specified in the Electrical Characteristics table.
Use Equation 6 to calculate the value of the pullup resistor.
