*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 operation sections of the specifications is
not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
