SI86SL42EE-AS2R

Digital Isolators Overview

The SI86SL42EE-AS2R is a low-power digital isolator from the Si86SL4x series, manufactured by Skyworks Solutions. It features four unidirectional channels with capacitive coupling technology. The device provides 6.0 kVrms isolation voltage and supports data rates up to 150 Mb/s. It operates within a supply voltage range of 2.375 V to 5.5 V and exhibits a propagation delay of 8 ns. Designed for automotive applications, it holds AEC-Q100 qualification and functions reliably across an operating temperature range of -40°C to +125°C. The component is housed in a 16-pin SOIC-WB package.

Digital Isolators Feature Summary

• Provides robust galvanic isolation using capacitive coupling technology for high noise immunity.
• Optimized for low power consumption suitable for energy-efficient system designs.
• Engineered for automotive environments with certified reliability standards.

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing reliable signal transmission across potential differences
• Power electronics monitoring circuits demanding high voltage isolation

Digital Isolators Procurement Notes

Verify the specific suffix AS2R indicates reel packaging configuration when sourcing. Confirm that the part meets current AEC-Q100 automotive grade requirements for your target application environment. Ensure compatibility with the 16-pin SOIC-WB footprint during PCB layout. Check manufacturer documentation for any recent product change notifications affecting specifications or materials.

Digital Isolators Selection Notes

Choose this component when four independent unidirectional isolation channels are required in a compact form factor. The 6.0 kVrms rating offers higher isolation capability compared to standard 5 kVrms options. Consider the 150 Mb/s speed limit against system timing requirements. The automotive qualification makes it suitable for harsh environmental conditions where standard industrial parts may fail.

Digital Isolators Part Context

This device belongs to the Si86SL4x family of digital isolators, which emphasizes low power and high performance. The family utilizes CMOS technology to achieve robust isolation without magnetic components. This specific model represents the automotive-grade variant designed for stringent reliability standards in vehicle electronics and industrial machinery.

Digital Isolators Replacement Considerations

SI86SL42HC-IS1R: Lower isolation rating (3.75 kVrms) and non-automotive grade. SI86SL41EE-AS2: Single channel instead of four. SI8642ED-AS2: Different channel polarity configuration and lower isolation rating (5 kVrms). Verify pinout and electrical parameters before substitution.
