† NOTICE: Stresses above those listed under “Absolute 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 operation listings of this specification is not implied. Exposure to maximum rating conditions for 
extended periods may affect device reliability.
