Stresses beyond those ratings listed under
“Absolute Maximum Ratings” may cause perma-
nent damage to the device. This is a stress rating
only and functional operation of the device at
these or other conditions beyond those indicated
in the operational sections of this specification is
not implied. Exposure to absolute maximum rat-
ing conditions for extended periods may affect
device reliability.
