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.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical characteristic specifications do not

apply when operating the device outside of its rated operating conditions.

(2)

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

specifications.

(3)

For operating at elevated temperatures, the device must be derated based on a maximum junction to case thermal resistance of 45°C

per watt, or 150°C per watt junction to ambient. (See Curves in the SPECIFIED PERFORMANCE CHARACTERISTICS section).

(4)

For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.

(5)

Continuous short circuit is allowed for case temperatures to +125°C and ambient temperatures to +70°C.
