COMMENT

Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only; the functional operation of

the device (at these or any other conditions above

those listed in the operational sections of this speciﬁca-

tion) is not implied. Exposure to absolute maximum rat-

ing conditions for extended periods may affect device

reliability.
