HCPL-091J-500E

Overview

The HCPL-091J-500E is a quad, bidirectional CMOS high-speed digital isolator from Broadcom. It provides four independent channels with a data rate of 110MBd and isolation voltage of 2500Vrms. The device features a common mode transient immunity (CMTI) of 15kV/µs and operates within a temperature range of -40°C to +85°C. Packaged in a 16-pin SOIC (3.90mm width), it supports logic levels from 1.7V to 5.5V.

Feature Summary

• Quad bidirectional channel architecture for versatile signal routing
• High-speed performance supporting 110MBd data rates
• Robust transient immunity against common mode noise
• CMOS technology ensuring low power consumption

Applications

• Industrial automation control systems
• Power supply feedback loops
• Medical equipment signal isolation
• Data acquisition systems

Procurement Notes

Verify the specific suffix '500E' to confirm RoHS compliance and tape-and-reel packaging configuration. Ensure the selected variant matches the required operating temperature range and pinout compatibility for your PCB layout. Cross-reference official datasheets for any recent package dimension updates or certification changes before finalizing procurement orders.

Selection Notes

Select this component when multiple isolated bidirectional signals are required in a compact footprint. The 16-pin SOIC package offers a balance between channel density and thermal management. Consider the 15kV/µs CMTI rating for environments with rapid voltage switching. Verify that the input voltage range aligns with the driving logic family used in the design.

Part Context

This part belongs to the HCPL series of digital isolators, which utilize asymmetric magnetic coupling technology. Unlike traditional optocouplers, these devices offer higher reliability and consistent performance over time. The series includes single, dual, and quad-channel variants designed to replace legacy optical isolation solutions in modern high-speed digital applications.

Replacement Considerations

Direct replacements include other quad-channel digital isolators from Broadcom such as the HCPL-0912 series. Check pin-to-pin compatibility and ensure the replacement maintains the same 2500Vrms isolation rating and 110MBd speed capability. Verify that the alternative device meets the same automotive or industrial qualification standards if applicable.
