Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix to confirm packaging type (tube vs. tape/reel) and temperature grade. Confirm that the selected variant meets the required isolation voltage and CMTI specifications for the target application environment. Cross-reference the datasheet revision date to ensure compliance with current regulatory standards.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transmission up to 20 Mb/s is required alongside robust electrical isolation. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Ensure the operating temperature range (-40°C to +100°C) aligns with the system's thermal constraints.
