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 may occur to the device. Operating Ratings indicate conditions for
which the device is intended to be functional. For specifications, see Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by T
JMAX
(maximum junction temperature), θ
J-A
(junction to ambient thermal resistance) and T
A
(ambient temperature). The maximum power
dissipation at any temperature is: P
DissMAX
= (T
JMAX
- T

) /θ
J-A
up to the value listed in the Absolute Maximum Ratings. θ
