(1) “Absolute Maximum Ratings” are those beyond which the safety of the device cannot be verified. They are not meant to imply that the
device should be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(3) Derate linearly @ 6.11 mW/°C to 400 mW at 70°C.
(4) Derate linearly at 5.56 mW/°C to 650 mW at 70°C.
