Note 1: Stresses beyond those listed under “Absolute maximum Ratings” may cause permanent damage to

the device. These are stress ratings only and functional operation of the device at these or any other

conditions beyond those indicated in the operational sections of the specifications are not implied. Exposure

to absolute maximum rating conditions for extended periods may affect device reliability.
