These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions 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) This value is limited to 2.5 V maximum. (4) The package thermal impedance is calculated in accordance with JESD 51-7.

The differential inputs must not be floating unless RESET is low.
