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.
PACKAGE AND ORDERING INFORMATION
For the most current package and ordering information, see the Package Option Addendum at the end of this
document, or see the TI Web site at www.ti.com.
Package drawings, thermal data, and symbolization are available at www.ti.com/packaging.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltage
values are with respect to AGND, unless otherwise stated.
