Logic Output Optoisolators Procurement Notes

Verify the specific suffix '-300' indicates the gull-wing lead form variant distinct from standard straight leads. Confirm RoHS compliance status through official documentation as historical Class K parts may have specific regulatory statuses. Ensure the ceramic package integrity matches application requirements for hermetic sealing. Cross-reference the manufacturer part number against current availability lists to confirm active status.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required alongside high-speed digital signaling. The ceramic construction suits environments where moisture resistance and long-term stability are critical. Compare propagation delay specifications against system timing constraints. Evaluate thermal management needs based on the 200 mW power dissipation limit under maximum operating conditions.
