SI86S660BB-IUR

Digital Isolators Overview

The SI86S660BB-IUR is a Skyworks Solutions digital isolator featuring six unidirectional channels with capacitive coupling technology. It operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 150 Mbps. The device provides an isolation voltage of 2500 Vrms and exhibits a minimum common-mode transient immunity of 100 kV/µs. Maximum propagation delay is specified at 14 ns, with typical rise and fall times of 2.5 ns. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in a 16-SSOP package.

Digital Isolators Feature Summary

• Six-channel unidirectional signal transmission via capacitive coupling
• High-speed data transfer capability supporting 150 Mbps rates
• Robust noise immunity characterized by 100 kV/µs common-mode transient rejection
• Automotive-grade qualification compliant with AEC-Q100 standards

Digital Isolators Applications

• Isolated SPI communication interfaces
• Industrial automation control systems
• Automotive electronic subsystems requiring galvanic isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'IUR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SSOP footprint matches the target PCB design constraints. Ensure compatibility with the intended supply voltage levels between 2.25 V and 5.5 V. Check for any recent product change notices regarding manufacturing site or material composition updates.

Digital Isolators Selection Notes

Select this component when high channel density is required for unidirectional data paths. The 100 kV/µs CMTI rating makes it suitable for noisy environments where standard isolators may fail. Consider the 16-SSOP package size relative to available board space. Verify that the 14 ns maximum propagation delay meets the timing requirements of the specific communication protocol being isolated.

Digital Isolators Part Context

This part belongs to the SI86S series of general-purpose digital isolators from Skyworks Solutions. It is designed to replace traditional optocouplers in applications demanding higher speed, lower power consumption, and improved reliability. The series offers various channel counts and packaging options to accommodate diverse system integration needs.

Digital Isolators Replacement Considerations

Publicly confirmed substitute part numbers include SI86S660BB-AUR and SI86S660EB-IUR. These alternatives share similar electrical characteristics and pin configurations but may differ in packaging type or specific performance margins.
