HCPL-9030

Overview

The HCPL-9030 is a dual-channel digital isolator from Broadcom Limited, utilizing magnetic coupling technology for signal transmission. It operates with a data rate of 100 Mb/s and provides an isolation voltage of 2500 Vrms. The device features unidirectional polarity and supports supply voltages between 3 V and 5.5 V. Key electrical parameters include a propagation delay of 15 ns and a common-mode transient immunity of 15 kV/µs. Operating temperatures range from -40°C to +100°C, and it is housed in an 8-pin DIP package.

Feature Summary

• High-speed performance with 100 Mb/s data rate capability
• Excellent transient immunity specifications for noisy environments
• Dual-channel configuration supporting full-duplex operation

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety barriers
• Power electronics control circuits

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Check current availability as the product lifecycle status may indicate end-of-life conditions. Ensure packaging type matches assembly requirements. Validate pinout compatibility with existing PCB layouts.

Selection Notes

Select this component when bidirectional isolation is not required, as it is unidirectional only. Consider the 15 ns propagation delay for timing-sensitive applications. Evaluate power consumption against system constraints given the specified operating currents. Ensure the 2500 Vrms isolation rating meets safety standards for the target application environment.

Part Context

This part belongs to the HCPL-90xx series of CMOS digital isolators. The series offers high-speed performance and robust transient immunity. Available in 8-pin PDIP packages, these devices are designed for general-purpose isolation tasks. The HCPL-9030 specifically provides dual-channel unidirectional isolation capabilities.

Replacement Considerations

HCPL-9030-000E is a verified substitute within the same family.
