Thermal performance is directly linked to the PCB design and ParameterRating operating environment. Careful attention to PCB thermal Storage Temperature Range (T design is required. ST) −55°C to +150°C Junction Operating Temperature −40°C to +150°C θJA is the junction to ambient thermal resistance, and ΨJT is the Range (TJ) junction to top characterization parameter.

VIN+ is rated up to 6.5 V when VDD1 is unpowered. 2 |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. Table 9.
