Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix (e.g., -560E, -500E, -000E) against the required tape-and-reel quantity or packaging specification, as these variants differ in shipping format rather than electrical function. Confirm that the component meets RoHS compliance requirements for the intended market. Ensure the SOIC-8 footprint matches the PCB design constraints. Check availability status, as some variants may be discontinued or subject to supply limitations.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required between circuits with different ground potentials. The 15 Mb/s data rate supports fast serial communication protocols. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 3750 Vrms isolation voltage for safety-critical applications. Verify that the operating temperature range of -40°C to 100°C aligns with the environmental conditions of the target application.
