HCPL-900J-000E

Overview

The HCPL-900J-000E is a high-speed CMOS digital isolator from the Broadcom HCPL-90xx series, housed in a 16-pin SOIC-Narrow package. It provides four independent channels with unidirectional signal transmission. The device supports data rates up to 100 Mb/s and features a symmetric magnetic coupling barrier for isolation. Key electrical specifications include an insulation voltage of 2500 Vrms, a common-mode transient immunity (CMTI) of 15 kV/µs, and a propagation delay of 15 ns. It operates on a supply voltage range of 3 V to 5.5 V, with power consumption varying by channel activity.

Feature Summary

• Symmetric magnetic coupling barrier technology ensures high reliability and excellent transient immunity.
• CMOS architecture delivers high-speed performance with low power consumption profiles.
• Four-channel configuration allows for parallel data isolation within a compact surface-mount package.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensors.
• Medical equipment needing safe separation between patient-connected circuits and processing units.
• Power electronics interfaces for monitoring and controlling inverters or motor drives.

Procurement Notes

Verify the specific suffix J-000E against your bill of materials to ensure compatibility with required packaging and lead times. Confirm that the 16-SOIC footprint matches your PCB design constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your system's thermal requirements.

Selection Notes

Select this component when high common-mode transient immunity is critical for noise rejection in electrically noisy environments. The 4-channel count suits applications requiring multiple isolated signals without increasing board space significantly. Consider the 100 Mb/s speed limit; higher speeds may require alternative models from the same family. Verify that the 2500 Vrms isolation rating aligns with safety standards for your specific application voltage levels.

Part Context

This part belongs to the Broadcom HCPL-90xx and HCPL-09xx families of CMOS digital isolators. These devices are designed to replace traditional optocouplers in many high-speed applications. The family shares similar magnetic coupling technology but varies in channel count and speed ratings. The HCPL-900J-000E represents the standard 4-channel variant within this high-performance isolator lineup.

Replacement Considerations

HCPL-090J-000E is a documented substitute within the same product family, offering identical functional specifications and pinout compatibility. Both parts utilize the same symmetric magnetic coupling barrier and CMOS technology. Verify that any replacement matches the exact suffix requirements for packaging and regional compliance before integration.
