Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix matches the required package type and lead time requirements. Confirm that the manufacturer's RoHS compliance status aligns with project environmental regulations. Ensure the procurement source is authorized to guarantee component authenticity and traceability. Check for any recent product change notices or obsolescence warnings from Broadcom before finalizing orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is necessary with direct drive capability. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 3750 Vrms isolation rating for safety compliance in mains-connected applications. Evaluate the 25 Mb/s data rate against system timing requirements to ensure adequate signal bandwidth.

Logic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers manufactured by Broadcom Limited. It is designed for applications demanding rapid signal transfer and robust noise rejection.
