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. Operating Ratings indicate conditions for

which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test

conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance

characteristics may degrade when the device is not operated under the listed conditions.

If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

(3)

The Human Body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. The machine model is a 200pF

capacitor discharged directly into each pin.

(4)

The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal

resistance,

θJ-A, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperture is calculated

using:

Where the value of

θJ-A for the micro SMD package is 220°C/W.
