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 indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test
conditions, see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(3) Human Body Model is 1.5 kΩ in series with 100 pF.
(4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature at 150°C.
(5) The maximum power dissipation is a function of T_J(MAX), θ_JA and T_A. The maximum allowable power dissipation at any ambient
temperature is P_D = (T_J(MAX) − T_A)/θ_JA. All numbers apply for packages soldered directly into a PC board.
