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 Recommended Operating Conditions is not implied. Operating Range conditions indicate

the conditions at which the device is functional and the device should not be operated beyond such conditions. For ensured

specifications and conditions, see the Electrical Characteristics table.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

(3)

Peak is the dc plus transient voltage including switching spikes.

(4)

Human Body Model (HBM) is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. Applicable standard is JESD22-

A114C. All pins pass 2 kV HBM except VDD, VIN and VCC which are rated for 1.5 kV.
