HCPL-902J-500

Overview

The HCPL-902J-500 is a general-purpose digital isolator featuring four independent channels in a 16-SOIC package. It provides 2500Vrms isolation voltage and supports data rates up to 110MBd with a common-mode transient immunity of 15kV/µs. The device operates on a single supply voltage ranging from 3V to 5.5V, drawing typical quiescent currents of 1.5mA per channel. It functions within an industrial temperature range of -40°C to +100°C and utilizes magnetic coupling technology for signal transmission.

Feature Summary

• High-speed digital signal transmission with 110MBd data rate capability
• Robust isolation performance with 2500Vrms rating and 15kV/µs CMTI
• Four-channel configuration in a compact 16-pin narrow SOIC package
• Wide operating voltage range supporting 3V to 5.5V logic levels

Applications

• Isolating data conversion devices such as ADCs and DACs
• Digital fieldbus isolation in industrial communication networks
• Parallel bus isolation for high-density data interfaces
• Peripheral interface isolation in embedded systems

Procurement Notes

Verify the specific suffix 'E' when ordering, as it denotes RoHS compliance and tape-and-reel packaging. Confirm availability status, as this part number may be obsolete or superseded by newer revisions. Ensure the required quantity matches the standard reel size if bulk procurement is intended. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when four isolated channels are required in a single package to save board space. It is suitable for applications demanding high common-mode transient immunity to prevent noise-induced errors. Consider the 16-SOIC footprint for PCB layout constraints. Verify that the 110MBd speed meets the system's timing requirements without introducing excessive propagation delay.

Part Context

This device belongs to the HCPL-900J series of CMOS digital isolators manufactured by Broadcom Limited. The series is designed for high-speed, high-density isolation applications. The HCPL-902J variant specifically offers four channels, distinguishing it from dual-channel models like the HCPL-901J. These components are widely used in industrial automation and data acquisition systems requiring reliable galvanic isolation.

Replacement Considerations

The HCPL-902J-500 is listed as obsolete. Direct substitutes include the HCPL-902J-500E, which maintains similar electrical characteristics but includes environmental compliance features. Check for pin-compatible alternatives from the same manufacturer family before considering cross-brand replacements.
