HCPL-901J

Overview

The HCPL-901J is a general-purpose, high-speed digital isolator featuring four independent channels. It utilizes magnetic coupling technology to transfer digital signals across an isolation barrier with a data rate of 100 MBd and a common-mode transient immunity of 15 kV/µs. The device supports a maximum supply voltage of 5.5 V and offers an isolation voltage rating of 2500 Vrms. Packaged in a 16-SOIC format, it provides bidirectional signal transmission capabilities, making it suitable for applications requiring robust noise immunity and high channel density.

Feature Summary

• High channel density design ideal for isolating parallel buses and peripheral interfaces
• Excellent transient immunity specifications ensuring reliable signal integrity
• Bidirectional configuration supporting two channels in each direction

Applications

• Isolating data conversion devices
• Parallel bus isolation
• Peripheral interface isolation

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel options. Ensure the component meets required isolation voltage ratings for the target application. Cross-reference the datasheet for exact electrical characteristics and thermal performance limits before integration into the design.

Selection Notes

Select this component when high-speed bidirectional communication is required between isolated domains. Consider the 16-pin SOIC footprint for PCB layout constraints. Evaluate the 15 kV/µs CMTI rating against system noise environments to ensure adequate protection against false triggering during fast transients.
