The valid common mode range is from device ground to VS – 1.5 V (VS – 2 V across temperature). Inputs may exceed VS up to the maximum VS without device damage. At least one input must be in the valid input common-mode range for the output to be the correct phase. If both inputs exceed the valid range, then the output phase is undefined. If either input more than 0.3 V below V– then input current should be limited to 1 mA and the output phase is undefined.
