SI8662AB-B-IS1R

Digital Isolators Overview

The SI8662AB-B-IS1R is a six-channel digital isolator from Skyworks Solutions, utilizing capacitive coupling technology. It features unidirectional signal transmission with four forward and two reverse channels. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports data rates up to 1 Mb/s. Key electrical parameters include a propagation delay of 35 ns, rise/fall times of 4 ns, and an insulation voltage of 2500 Vrms. It is qualified under AEC-Q100 standards for automotive applications and functions across a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Capacitive isolation technology providing high common-mode transient immunity
• AEC-Q100 qualification for automotive reliability requirements
• Unidirectional channel configuration for isolated signal transmission

Digital Isolators Applications

• Automotive power electronics isolation
• Industrial communication bus interfaces
• General-purpose isolated data transfer

Digital Isolators Procurement Notes

Verify the specific suffix IS1R corresponds to the required tape and reel packaging format. Confirm that the unidirectional channel arrangement meets the system's signal flow requirements. Ensure the 2500 Vrms insulation rating aligns with the safety isolation standards of the target application environment.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is sufficient for the design. The 1 Mb/s data rate suits lower-speed control signals rather than high-bandwidth data links. Consider the SOIC-Narrow-16 package constraints for PCB layout density and thermal management capabilities.

Digital Isolators Part Context

This part belongs to the Si86xx series of digital isolators. It shares the same physical footprint and basic interface characteristics as other variants in the family, such as the SI8663AB-B-IS1R, but differs in internal channel directionality and specific electrical timing parameters defined by its model designation.

Digital Isolators Replacement Considerations

SI8663AB-B-IS1R offers similar specifications but with a symmetric 3-forward/3-reverse channel configuration instead of the 4-forward/2-reverse layout found in the SI8662AB-B-IS1R.
