Electrical Specifications

Notice†: Stresses above those listed under “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.
