HCPL-0930

Overview

The HCPL-0930 is a dual-channel digital isolator from Broadcom Limited, utilizing magnetic coupling technology for signal transmission. It features unidirectional channel configuration and operates within a supply voltage range of 3 V to 5.5 V. The device supports data rates up to 110 MBd with a maximum propagation delay of 15 ns. It provides an insulation voltage of 2500 Vrms and exhibits common mode transient immunity of 15 kV/µs. Packaged in an SOIC-8 surface-mount format, it functions reliably across temperatures from -40°C to +100°C.

Feature Summary

• High-speed performance with excellent transient immunity specifications
• Dual-channel unidirectional configuration for full-duplex operation
• Magnetic coupling isolation technology ensuring robust signal integrity

Applications

• General purpose digital isolation in industrial systems
• Signal isolation in measurement and control circuits
• Isolation interfaces for microcontroller-based applications

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel options. Ensure compatibility with system voltage levels and thermal requirements. Confirm RoHS compliance status through official documentation. Check lead times as production cycles may vary. Validate pinout alignment with existing PCB footprints before integration.

Selection Notes

Select this component when high-speed bidirectional communication is not required, as channels are unidirectional. Consider the 15 ns propagation delay for timing-critical designs. Evaluate power consumption against system constraints, noting the low quiescent current. Ensure the SOIC-8 package fits the available board space. Verify that the 2500 Vrms isolation rating meets safety standards for the application.

Part Context

This part belongs to the HCPL-09xx series of CMOS digital isolators designed for general-purpose applications. The series includes both unidirectional (HCPL-0930) and bidirectional (HCPL-0931) variants. These devices offer a compact solution for replacing traditional optocouplers in modern electronic designs requiring reliable galvanic isolation.

Replacement Considerations

Direct substitutes include other HCPL-09xx series devices such as HCPL-0931 for bidirectional needs. Cross-reference with similar magnetic isolators from other manufacturers if availability is constrained. Ensure functional equivalence in terms of isolation voltage and data rate when considering alternative sources.
