*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 perma-

nent 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.
