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, 1.5 kΩ in series with 100 pF.
(4) Applies to both single-supply and split-supply operation. Continuous short operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature at 150°C. Output currents in excess of ±30 mA over long term may adversely
affect reliability.

(1) Typical Values represent the most likely parametric norm.
(2) All limits are specified by testing or statistical analysis.
(3) Specified limits are dictated by tester limits and not device performance. Actual performance is reflected in the typical value.
