HCPL-090J-500

Digital Isolators Overview

The HCPL-090J-500 is a high-speed digital isolator from Broadcom Limited, featuring four independent channels in a unidirectional configuration. It utilizes symmetric magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 2500 Vrms. The device supports data rates up to 110 MBd and operates within a supply voltage range of 3 V to 5.5 V. Key performance metrics include a propagation delay of 12 ns and a common-mode transient immunity of 15 kV/µs. It is housed in a 16-pin SOIC package.

Digital Isolators Feature Summary

• Unidirectional signal transmission across four isolated channels
• Symmetric magnetic coupling for high-speed data integrity
• High common-mode transient immunity for noise rejection

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive interfaces

Digital Isolators Procurement Notes

Verify the specific suffix '500' against the required RoHS compliance status, as this designation may indicate non-compliant variants compared to the 'E' suffix. Confirm package availability and lead times directly with authorized distributors or the manufacturer, as stock levels fluctuate. Ensure the unidirectional configuration matches the circuit design requirements before ordering.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is required for multi-channel digital signals. Compare against the HCPL-092J series if bidirectional communication is necessary. Consider the HCPL-090J-500E variant if RoHS compliance is mandatory for the target market. Evaluate the 15 kV/µs CMTI specification against the noise environment of the application.

Digital Isolators Part Context

This part belongs to the HCPL-900J/-090J family of quad-channel digital isolators. These devices are designed to replace traditional optocouplers in applications requiring higher speed and better reliability. The family includes both unidirectional and bidirectional variants, distinguished by their model suffixes and channel configurations.

Digital Isolators Replacement Considerations

The HCPL-090J-500E is a direct functional replacement that offers RoHS compliance while maintaining identical electrical specifications and pinout compatibility.
