Notes:
Stresses greater than those listed under MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and func-
tional 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.
