(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) 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 of 150°C.

(3) The maximum power dissipation is a function of T_J(MAX),R _θJA, and T_A. The maximum allowable power dissipation at any ambient temperature is P_D = (T_J(MAX) - T_A)/R _θJA. All numbers apply for packages soldered directly onto a PC board.

(4) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications.

(5) Output short circuit duration is infinite for V_S < 6 V at room temperature and below. For V_S > 6 V, allowable short circuit duration is 1.5ms.
