Note:
Stresses greater than those listed under MAXI-
MUM RATINGS may cause permanent 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 operational
sections of this specification is not implied.
Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
