(1) The SCL and SDA pins shall not be at a higher potential than the supply voltage VCC in the application, or an increase in leakage current, II, will result.
(2) The values shown apply to specific junction temperatures. See the Calculating Junction Temperature and Power Dissipation section on how to calculate the junction temperature.
