Rating assumes VDD1 is above 2.5 V. VI+ and VI− are rated up to 6.5 V when

VDD1 is unpowered.

2

Referenced to GND2, maximum of 40 V.

|CM| refers to common-mode transients across the insulation barrier.

Common-mode transients exceeding the Absolute Maximum Rating can

cause latch-up or permanent damage.

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 operating 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 thermal resistance,

junction to ambient (°C/W).
