These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 table of “Electrical Characteristics” provides 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 PDIP molded package 11.9 mW/°C above 25°C. Derate SOIC package 8.41 mW/°C above 25°C.
