Logic Output Optoisolators Procurement Notes

Verify the specific suffix #360 against the official datasheet to confirm the surface-mount gull-wing package variant. Ensure the selected part matches the required insulation clearance and creepage distances for your application's safety standards. Confirm RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when a high-speed logic output with integrated pull-up resistance is required for gate drive applications. The open-collector configuration allows flexibility in output voltage levels between 4.5V and 30V. Consider the 15kV/µs CMTI rating for environments with high dv/dt noise. Verify that the 1 MBd data rate meets the system's timing requirements.

Logic Output Optoisolators Part Context
