(1) “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be verified. They are not meant to imply
that the devices 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 Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) Derate CDIP package 8.7 mW/°C above 25°C; derate PDIP package 7.5 mW/°C above 25°C; derate SOIC package 6.5 mW°C above
