1 For voltages beyond these limits, use input protection resistors. See the

Theory of Operation section for more information.

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 junction to ambient thermal resistance, and θJC is the

junction to case thermal resistance.

ELECTROSTATIC DISCHARGE (ESD) RATINGS

The following ESD information is provided for handling of ESD-sen-

sitive devices in an ESD-protected area only.

Human body model (HBM) per ESDA/JEDEC JS-001-2011.

Charged device model (CDM) per JESD22-C101.

Machine model (MM) per JESD22-A115. MM voltage values are for

characterization only.

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.
