Operating Conditions
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.
