HCPL-900J-500E

Digital Isolators Overview

The Broadcom HCPL-900J-500E is a high-speed CMOS digital isolator featuring four independent channels within a single package. It operates with a data rate of 110 MBd and provides an isolation voltage of 2500 Vrms. The device exhibits a common-mode transient immunity (CMTI) of 15 kV/µs, ensuring robust signal integrity in noisy environments. It functions within a supply voltage range of 3 V to 5.5 V and supports bidirectional data transmission. The component is housed in a 16-pin SOIC narrow package and complies with AEC-Q100 automotive standards.

Digital Isolators Procurement Notes

Verify the specific suffix '500E' to confirm reel packaging and RoHS compliance status. Ensure the procurement source provides valid traceability documentation for automotive-grade components. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential lifecycle changes before finalizing orders.

Digital Isolators Selection Notes

Select this component when four isolated channels are required in a compact footprint. The 110 MBd speed suits applications needing faster data throughput than standard optocouplers. Verify that the system's common-mode noise does not exceed the 15 kV/µs rating. Confirm compatibility with the target logic family voltage levels between 3 V and 5.5 V.

Digital Isolators Part Context

This part belongs to the HCPL-90xx series of CMOS digital isolators from Broadcom. These devices utilize capacitive coupling technology rather than optical LEDs, offering longer lifespan and better temperature stability compared to traditional optocouplers. The series is designed to replace legacy optocoupler solutions in modern high-speed digital interfaces.

Digital Isolators Replacement Considerations

Direct pin-to-pin replacements may include HCPL-901J or HCPL-902J variants depending on channel count requirements. Verify that substitute parts maintain the same 15 kV/µs CMTI rating and 110 MBd speed. Check for equivalent automotive qualification status if used in vehicle applications.
