*COMMENT

Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only and the functional operation

of the device at these or any other conditions above

those listed in the operational sections of this speciﬁ-

cation is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect

device reliability.
