Operating Temperature. . . . . . . . . . . . -40C to +85C
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age 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.
