Logic Output Optoisolators Procurement Notes

Verify the specific suffix configuration against the datasheet to ensure correct packaging and lead-free status. Confirm that the selected variant matches the required operating temperature range and package dimensions for the target PCB layout. Cross-reference the manufacturer part number with official Broadcom documentation to validate authenticity and active lifecycle status before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when designing circuits that demand high-speed digital isolation with low propagation delay. The integrated enable pin allows for precise control over the output state, which is beneficial for reducing power consumption or managing bus contention. Ensure the design accommodates the 10 mA forward current requirement and verifies that the load connected to the open collector output can handle the specified voltage and current limits safely.

Logic Output Optoisolators Part Context

This device belongs to the HCPL series of high-speed optocouplers produced by Broadcom Limited. It serves as a specialized solution for isolating digital signals where speed and noise immunity are critical. The product represents a transition from traditional pulse transformers, offering a compact solid-state alternative for long-line drivers and buffer applications in industrial and computing environments.

Logic Output Optoisolators Replacement Considerations

Direct replacements must maintain the 8-pin SOIC footprint, 3750 Vrms isolation rating, and open collector output topology. Verify that any substitute component supports the 10 MBd data rate and compatible logic levels. Check for equivalent enable functionality and similar transition times to ensure system performance remains unchanged during integration.
