Absolute Maximum Ratings
Stresses greater than those listed may cause perma-
nent damage to the device. This is a stress rating only,
and functional operation of the device at these or any
other conditions above those indicated in the opera-
tional sections of this specification is not implied.
Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
