Absolute Maximum Ratings
The device contains circuitry to protect the inputs against damage due to high static voltages or electric fields;
however, precautions should be taken to avoid application of any voltage higher than the absolute maximum rated
voltages to this circuit. For proper operation, all Vin and Vout pins should be constrained to the range, VSS-0.5V <
( Vin or Vout) < VDD+0.5V. Refer to electrical specifications for operating supply range.
