Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging or temperature ranges. Confirm that the 8-DIP package dimensions meet your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the isolation voltage rating aligns with your system safety requirements.

Selection Notes

Select this component when bidirectional data transfer is required between isolated circuits. Consider the 110 MBd data rate capability for high-speed applications. Evaluate the 15kV/µs common-mode transient immunity for noisy environments. Verify that the dual-channel architecture fits your signal routing needs without requiring additional components.

Part Context

This part belongs to the HCPL-90xx series of CMOS digital isolators. The series includes unidirectional variants like the HCPL-9030 and other bidirectional models. These devices share similar core technologies but differ in channel directionality and specific electrical characteristics tailored for different isolation applications.

Replacement Considerations

Check for direct substitutes within the HCPL-90xx family. Verify pinout compatibility before swapping with similar isolators. Ensure replacement parts maintain the same isolation voltage and data rate specifications.
