These are stress ratingsonly, and functional operation of the device at these or any other conditions beyond those indicated under Recommended OperatingConditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.(2) The input and output negative voltage ratings may be exceeded if the input and output clamp-current ratings are observed.(3) SDA and SCL can go up to 3.6 V as stated in the Recommended Operating Conditions table.
