• Power electronics control circuits for noise immunity.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot codes against current datasheets. Check for obsolescence notices or lifecycle changes as the product may be subject to discontinuation. Ensure packaging specifications match project requirements for SMD assembly processes.

Selection Notes

Select this component when dual-channel isolation with magnetic coupling is required for high-speed digital signals. Consider the 2500 Vrms isolation rating and 100 Mb/s speed for compatibility with system timing and safety standards. Evaluate the 8-SMD package footprint against PCB layout constraints. Compare propagation delay and power consumption against alternative isolators if low latency or energy efficiency are critical design parameters.

Part Context

This part belongs to the HCPL-9030 series of general-purpose digital isolators. It is manufactured by Broadcom Limited, formerly Avago Technologies. The series includes variants with different pin configurations and channel counts, such as bidirectional options.
