*Static–sensitive device. Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses

above 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 above those indicated in the operational sections of the specifications is not

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