Unless otherwise specified, all pin names refer to both transceivers

on an ADBMS6822 with respect to the related power supply pins

(for example, CS2 relative to VDDS2).

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 resistance

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

to-case thermal resistance.

1 The exposed pad must be connected to the GND plane for proper thermal

management.

2 Board layout impacts thermal characteristics such as θJA.

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.
