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. Operating Ratings indicate conditions for

which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test

conditions, see the Electrical Characteristics.

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

specifications.

Ω in series with 100pF.

(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 of 150°C.

(5)

The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient

temperature is PD = (TJ(MAX) − TA)/θJA. All numbers apply for packages soldered directly into a PC board.

(1)

Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very

limited self-heating of the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under

conditions of the internal self heating where TJ > TA.

(2)

Typical values represent the most likely parametric norm.

(3)

All limits are guaranteed by testing or statistical analysis.
