Logic Output Optoisolators Procurement Notes

Verify the specific suffix for ordering requirements, as variants such as HCPL-061N#500 or HCPL-061N-000E exist. Confirm availability status, as some listings indicate discontinued or out-of-stock conditions. Ensure the selected variant matches the required packaging and RoHS compliance specifications for your manufacturing process.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required within a compact surface-mount footprint. The open-collector output necessitates an external pull-up resistor; ensure the supply voltage and resistance values align with the target logic family. Verify that the 3750 Vrms isolation rating meets the safety standards of the application environment.

Logic Output Optoisolators Part Context

This device belongs to the Broadcom HCPL-061A/HCPL-061N family of logic-output optocouplers. These components are designed to replace older discrete transistor-optical couplers, offering improved speed and reliability. The family shares similar pinouts and functional characteristics, facilitating direct upgrades in existing circuit designs.

Logic Output Optoisolators Replacement Considerations

Direct replacements include HCPL-061A and HCPL-061N-000E. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure the alternative part number meets the same isolation voltage and data rate requirements.
