CHARACTERISTICS
“Maximum Ratings” 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
listings of this specification is not implied. Exposure to
maximum rating conditions for extended periods may
affect device reliability.
