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) All voltage values (except differential voltages and VCC specified for the measurement of IOS) are with respect to the network GND. (3) Differential voltages are at IN+, with respect to IN−.
