HCPL-092J

Overview

The HCPL-092J is a quad-channel CMOS digital isolator featuring high-speed performance and excellent transient immunity. It operates with a data rate of 100 Mb/s and provides an isolation voltage of 2500 Vrms using magnetic coupling technology. The device supports bidirectional signal transmission and is compatible with 3.3V and 5V CMOS logic levels. It functions within a supply voltage range of 3 V to 5.5 V, drawing a typical operating current of 1.5 mA or 3 mA depending on the channel configuration. Propagation delay is specified at 15 ns, ensuring precise timing for high-speed applications.

Feature Summary

• High-speed CMOS digital isolation with 100 Mb/s data rate capability
• Excellent common-mode transient immunity specifications
• Bidirectional signal transmission across four independent channels
• Compatible with standard 3.3V and 5V CMOS logic families

Applications

• General-purpose digital signal isolation in industrial systems
• Isolation of microcontroller interfaces and communication buses
• Signal conditioning in noisy electromagnetic environments
• Power management circuit feedback loops

Procurement Notes

Verify the specific suffix code (e.g., -000E) against the manufacturer's datasheet to confirm pinout orientation and packaging type. Ensure the required isolation voltage rating meets system safety standards. Confirm that the 16-pin SOIC-Narrow package fits the PCB footprint constraints. Check for RoHS compliance requirements if applicable to the final assembly.

Selection Notes

Select this component when bidirectional isolation is required for multiple signals simultaneously. The 4-channel configuration reduces board space compared to single-channel alternatives. Verify that the 15 ns propagation delay aligns with the system timing budget. Consider the 2500 Vrms isolation barrier strength relative to the application's electrical stress requirements.

Part Context

This part belongs to the Broadcom HCPL series of digital isolators. It utilizes magnetic coupling technology rather than optical components, offering higher reliability and faster switching speeds. The series is designed to replace traditional optocouplers in high-speed digital applications requiring robust noise immunity and compact form factors.

Replacement Considerations

Check for direct substitutes such as the HCPL-092J-500E variant, which may differ only in tape-and-reel packaging. Verify pin compatibility before replacing with other quad-channel isolators from different manufacturers.
