Stresses above those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the
device. This is a stress rating only and the 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 device reliability.
DC OPERATING CHARACTERISTICS
Temperature = -40°c to +85°c, unless otherwise stated.
