Procurement Notes

Verify the specific suffix 'SOAR' corresponds to the SOP8 package variant with 3750 VRMS isolation rating. Confirm that the component meets the required safety certifications such as UL 1577 or VDE depending on the target application region. Ensure the operating temperature range of -40°C to +125°C aligns with system thermal constraints. Cross-reference the datasheet for any pending certification statuses that may affect final product approval.

Selection Notes

Select this component when dual-channel isolation is required with high-speed data rates exceeding standard optocoupler capabilities. The wide supply voltage range allows flexibility in interfacing with various logic families without additional level shifting. Consider the SOP8 footprint for space-constrained designs where WSOP variants are not feasible. Evaluate the CMTI specification against the noise environment of the application to ensure signal integrity.
