† 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 operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability. Static-sensitive device. Store only in conductive containers. Handling personnel and

equipment should be grounded to prevent damage from static discharge.
