Notes : (1)
Stresses above those listed may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at those or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
