Note: The 82551IT maximum rating for the Ambient Temperature is -40° C to 85° C.
Stresses above the listed absolute maximum ratings may cause permanent damage to the 82551QM
device. This is a stress rating only and functional operations 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 device
reliability.
