1 Values relate to package being used on a standard 2-layer PCB. This gives a

worst case θJA and θJC. Refer to Figure 3 for a plot of maximum power

dissipation vs. ambient temperature (TA).

2 TA = ambient temperature.

3 Junction-to-case resistance is applicable to components featuring a

preferential flow direction, for example, components mounted on a heat

sink. Junction-to-ambient resistance is more useful for air-cooled, PCB-

mounted components.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on

the human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degrada-

tion or loss of functionality.
