HCPL-9000-300

Overview

The HCPL-9000-300 is a single-channel digital isolator from the HCPL-9000 series, manufactured by Broadcom Limited. It utilizes symmetric magnetic coupling technology to provide electrical isolation between circuits. The device features a bidirectional data path with a maximum data rate of 100 Mb/s and a propagation delay of 15 ns. It offers an isolation voltage of 2500 Vrms and a minimum common-mode transient immunity of 15 kV/µs. Operating on a supply voltage range of 3V to 5.5V, it draws 8 µA in standby and 3.3 mA during active operation. The component is housed in an 8-pin DIP Gull Wing surface-mount package and supports -40°C to +100°C operating temperatures.

Feature Summary

• Employs symmetric magnetic coupling barrier technology for high-speed signal transmission
• Provides bidirectional data flow capability within a single channel configuration
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments
• Compatible with standard TTL and CMOS logic levels at 3.3V and 5V supplies

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing certified safety isolation barriers
• Power electronics interfaces for gate drive isolation
• General-purpose digital communication links across isolated domains

Procurement Notes

Verify RoHS compliance status carefully as sources indicate non-compliance due to lead content. Confirm availability as the part may be discontinued or restricted. Ensure the specific suffix matches required packaging and environmental standards. Check for valid UL and IEC certifications if safety isolation is mandated for the application design.

Selection Notes

Select this component when a single bidirectional channel is sufficient for the isolation requirement. Consider the 15 ns propagation delay and 100 Mb/s speed limit against system timing constraints. Evaluate the 8-pin SMD footprint compatibility with PCB layout. Verify that the 2500 Vrms isolation rating meets the specific safety standards required by the end product regulations.

Part Context

This device belongs to the HCPL-90xx series of high-speed CMOS digital isolators. The series includes unidirectional and bidirectional variants in single, dual, and quad-channel configurations. The HCPL-9000-300 specifically denotes the single-channel bidirectional version in the gull-wing surface mount package. It shares core magnetic coupling technology with other members of the family but differs in channel count and directionality.

Replacement Considerations

Direct substitutes include other single-channel bidirectional isolators from the same series such as HCPL-9000 variants with different suffixes for packaging or temperature ratings. Cross-brand replacements require matching the 2500 Vrms isolation, 100+ Mb/s data rate, and 8-pin gull-wing package dimensions.
