NOTES:

1. This specification applies over the full operating temperature range.

2. IPULLUPAC varies with temperature and VCC voltage, as shown in the Typical Performance Characteristics section.

3. The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function of the

pull-up resistor and VCC voltage is shown in the Typical Performance Characteristics section.

4. Guaranteed by design, not production tested.

5. CB = total capacitance of one bus line in pF.

6. SDA_IN/SCL_IN = 0.1 V, SDA_OUT/SCL_OUT through resistor to VCC.

7. Delays that can occur after ENABLE and/or idle times have passed.
