SI86S663EC-IS1R

Digital Isolators Overview

The SI86S663EC-IS1R is an automotive-grade digital isolator from Skyworks Solutions, featuring six unidirectional channels with capacitive coupling technology. It provides a high isolation voltage of 3.75 kVrms and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.5 V to 5.5 V and exhibits a propagation delay of 8 ns. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C. Packaged in a SOIC-NB-16 format, it ensures robust signal integrity in noisy environments.

• Inverter gate drive circuits
• Industrial automation systems requiring galvanic isolation

Digital Isolators Procurement Notes

Verify the specific suffix IS1R indicates reel packaging when sourcing components. Confirm that the EC designation aligns with automotive grade requirements for your specific application environment. Ensure compatibility with standard SOIC-NB-16 footprints during PCB layout integration. Cross-reference official datasheets for any recent product change notifications affecting pinout or electrical characteristics.

Digital Isolators Selection Notes

Select this component when high channel density and automotive reliability are required. The six-channel configuration reduces board space compared to single-channel alternatives. Capacitive coupling offers superior noise immunity over magnetic options. Verify that the 150 Mb/s data rate meets system timing requirements before finalizing the design choice.

Digital Isolators Part Context

This part belongs to the Si86S6x series of automotive digital isolators. It complements other Skyworks isolation products by offering multi-channel solutions. The series is designed to replace optocouplers in modern automotive architectures. It shares package dimensions with similar industrial variants but differs in qualification standards.

Digital Isolators Replacement Considerations

Direct substitutes include SI86S661EC-IS1R and SI86S663EC-AS1R. These parts share identical pinouts and functional specifications. Verify that the alternative suffix matches the required packaging type. Ensure the replacement maintains the same AEC-Q100 automotive qualification status.
