Logic Output Optoisolators Procurement Notes

Verify the specific suffix '060E' to ensure the correct through-hole PDIP packaging and RoHS compliance status. Confirm that the 3 mA forward current rating aligns with your circuit design requirements, as other variants may support different input currents. Cross-reference the manufacturer datasheet for detailed mechanical dimensions and thermal characteristics before finalizing procurement specifications.

Logic Output Optoisolators Selection Notes

Select this component when high-speed isolation is required for single-channel applications. The open collector output necessitates an external pull-up resistor; ensure the resistor value matches the desired logic levels and load conditions. Consider the 3 mA drive requirement against available microcontroller GPIO capabilities. Verify that the 3750 Vrms isolation meets safety standards for the target application environment.

Logic Output Optoisolators Part Context

This part belongs to the HCPL family of high-speed optocouplers designed for demanding industrial and communication applications. It complements similar models like the HCPL-2611 by offering specific packaging and current drive options within the same performance class. The series is characterized by fast response times and reliable isolation for protecting sensitive control circuits.

Logic Output Optoisolators Replacement Considerations

HCPL-2611-060E offers identical pinout and performance but typically specifies a 5 mA forward current instead of 3 mA. Ensure the driving circuit can accommodate the slightly higher current requirement if substituting directly without redesigning the input stage.
