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 does not ensure specific performance limits. For ensured specifications and conditions,
see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. Test Method is per JESD-22-A114.
(4) For detailed information on soldering plastic TSSOP and WSON packages, please refer to Application Note AN-1520: A Guide to Board
Layout for Best Thermal Resistance for Exposed Packages (literature number SNVA183), Application Note AN-1187 (literature number
SNOA401), or go to www.ti.com/packaging for more information.
