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, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Operating Ratings is not implied. The recommended Operating Ratings indicate
conditions at which the device is functional and the device should not be operated beyond such conditions. All voltages are with respect
to the potential at the AGND pin, unless otherwise specified.
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
Refer to http://www.ti.com/packaging for more detailed information and mounting techniques.
The human body model is a 100 pF capacitor discharged through a 1.5 k ? resistor into each pin. The applicable standard is JESD22-
A114C.
