HCPL-900J-500

Overview

The HCPL-900J-500 is a quad-channel digital isolator from Broadcom Limited, housed in a 16-SOIC package. It provides an isolation voltage of 2500Vrms and supports data rates up to 110MBd with a common mode transient immunity (CMTI) of 15kV/µs. The device operates on a supply voltage between 3V and 5.5V, drawing typical currents of 1.5mA or 3mA depending on the channel configuration. It functions within a temperature range of -40°C to +100°C.

Feature Summary

• Features symmetric magnetic coupling barrier technology for high-speed performance.
• Provides excellent transient immunity specifications for reliable signal transmission.
• Configured as unidirectional channels for general-purpose digital isolation.

Applications

• High-voltage isolation applications requiring robust signal integrity.
• Industrial systems utilizing CMOS digital interfaces.
• General-purpose digital isolation circuits needing high CMTI.

Procurement Notes

Verify the specific suffix 'E' against the datasheet to confirm RoHS compliance status if required by your manufacturing standards. Ensure the 16-SOIC package dimensions match your PCB footprint constraints. Confirm that the unidirectional channel configuration aligns with your circuit design requirements before finalizing procurement.

Selection Notes

Select this component when bidirectional isolation is not required, as the HCPL-900J series is configured for unidirectional data flow. Consider the 110MBd speed and 15kV/µs CMTI for noisy environments. Compare against the HCPL-090J series if bidirectional functionality is necessary instead. Ensure the 3V to 5.5V operating voltage range fits your system power rails.

Part Context

This part belongs to the HCPL-90xx family of CMOS digital isolators manufactured by Broadcom Inc. The family includes variants like HCPL-901J and HCPL-902J, which differ in channel directionality. These devices are designed for interface ICs requiring high-speed digital isolation with low power consumption and small form factor packages.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with HCPL-090J if bidirectional channels are needed, but note the functional difference in channel directionality.
