*COMMENT
Stresses above those listed under âAbsolute Maximum
Ratingsâ may cause permanent damage to the device.
This is a stress rating only and the functional operation
of the device at these or any other conditions above
those listed in the operational sections of this specifi-
cation is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect
device reliability.
