Attention: Permanent damage to the device may occur if “Absolute Maximum Ratings” are exceeded. This is a stress
rating only, and functional operation should be restricted to recommended operation conditions. Exposure
to absolute maximum rating conditions for extended periods of time may affect device reliability and
exceeding only one of the values may cause irreversible damage to the integrated circuit.
