Stresses at or above those listed under Absolute Maximum Ratings

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

rating only; functional operation of the product at these or any other

conditions above those indicated in the operational section of this

specification is not implied. Operation beyond the maximum operat-

ing conditions for extended periods may affect product reliability.

THERMAL RESISTANCE

Thermal performance is directly linked to printed circuit board

(PCB) design and operating environment. Careful attention to PCB

thermal design is required.

θJA is the natural convection, junction to ambient, thermal resist-

ance measured in a one cubic foot sealed enclosure. θJC is the

junction to case thermal resistance.

1 The thermal resistance values specified in Table 4 are simulated based

on JEDEC specifications (unless specified otherwise) and must be used in

compliance with JESD51-12.

Refer to the ESD Map section for a schematic of ESD diodes and

paths.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Charged devi-

ces and circuit boards can discharge without detection. Although

this product features patented or proprietary protection circuitry,

damage may occur on devices subjected to high energy ESD.

Therefore, proper ESD precautions should be taken to avoid

performance degradation or loss of functionality.
