Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed

performance limits and associated test conditions, see the Electrical Characteristics tables.

(2)

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 200 pF

capacitor discharged directly into each pin. MIL-STD-883 3015.7

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed

performance limits and associated test conditions, see the Electrical Characteristics tables.

All voltages are with respect to the potential at the GND pin.

Thermal Properties

Juntion-to-Ambient Thermal Resistance (

250°C/W

(1)

Junction-to-ambient thermal resistance is highly dependent on application and board layout. In applications where high maximum power

dissipation exists, special care must be paid to thermal dissipation issues in board design.
