HCPL-0900-000E

Overview

The HCPL-0900-000E is a unidirectional digital isolator manufactured by Broadcom Limited, housed in an 8-SOIC surface-mount package. It supports data rates up to 100 Mb/s with a propagation delay of 15 ns and pulse width distortion of 3 ns. The device operates on a supply voltage range of 3 V to 5.5 V, drawing typical currents of 8 uA and 3.3 mA. It provides 2500 Vrms isolation via magnetic coupling technology. Operating temperatures span from -40°C to +100°C, with power dissipation rated at 150 mW.

Feature Summary

• Utilizes giant magnetoresistive (GMR) magnetic coupling for signal transmission without optical components.
• Provides high-speed digital isolation suitable for demanding communication protocols.
• Features low power consumption characteristics optimized for energy-efficient designs.

Applications

• ATM Forum UNI SONET compliant interfaces
• High-speed digital isolation in industrial control systems
• Data acquisition systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix '000E' to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the SOIC-8 package matches your PCB footprint requirements. Check for active status and availability through authorized distributors to avoid counterfeit components. Ensure thermal management plans account for the 150 mW power dissipation rating under maximum operating conditions.

Selection Notes

Select this component when unidirectional isolation is required at speeds up to 100 Mb/s. The GMR technology offers advantages over traditional optocouplers regarding longevity and temperature stability. Consider the 2500 Vrms isolation barrier for safety-critical applications. Evaluate the 3 V to 5.5 V supply range compatibility with your system logic levels before finalizing the design.
