* Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the limits in the Electrical Characteristics tables
or Pin Descriptions section.
This device contains protection circuitry to
guard against damage due to high static volt-
ages or electric fields. However, precautions
must be taken to avoid applications of any volt-
age higher than maximum rated voltages to
this high–impedance circuit.
