SI86SO20BE-IS4

Digital Isolators Overview

The SI86SO20BE-IS4 is a general-purpose digital isolator from Skyworks Solutions, featuring two unidirectional channels with inverting outputs. It utilizes capacitive coupling technology to provide galvanic isolation rated at up to 6000 VRMS. The device supports high-speed data transmission rates of DC to 150 Mbps without requiring start-up initialization. It operates on a wide supply voltage range of 2.25 V to 5.5 V and is housed in an SSO-8 package.

Digital Isolators Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Supports high-speed operation with data rates up to 150 Mbps
• Features inverting output logic for two unidirectional signal paths
• Operates across a wide supply voltage range without start-up initialization

Digital Isolators Applications

• General-purpose digital isolation in industrial systems
• Isolating communication interfaces such as UART or SPI
• Protecting control circuits in automotive applications
• Signal isolation in measurement and sensing equipment

Digital Isolators Procurement Notes

Verify the specific suffix IS4 indicates tube packaging when sourcing components. Confirm that the inverting output configuration aligns with system logic requirements. Ensure the 6000 VRMS isolation rating meets safety standards for the intended application environment. Check for RoHS compliance documentation during procurement.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional channels. The inverting output characteristic must be accounted for in circuit design. Consider the SSO-8 package size for PCB layout constraints. Verify that the 150 Mbps speed is sufficient for the target data interface.

Digital Isolators Part Context

This part belongs to the Si86SO2x series of automotive-grade digital isolators. It shares the core capacitive isolation architecture with other members of the family but differs in channel count and output polarity. The series is designed for robust performance in electrically noisy environments.

Digital Isolators Replacement Considerations

SI86SO20EC-ASR offers similar isolation but may differ in packaging or output configuration. SI86S620EE-IS4 provides non-inverting outputs within the same isolation class. Verify pin compatibility and electrical specifications before substituting.
