This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated

* Absolute maximum continuous ratings are those values beyond which damage to the device
may occur. Exposure to these conditions or conditions beyond those indicated may adversely
affect device reliability. Functional operation under absolute–maximum–rated conditions is not
implied.
