COMMENT

Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only; functional operation of the

device (at these or any other conditions above those

listed in the operational sections of this speciﬁcation) is

not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device

reliability.
