SI8660AB-B-IS1R

Digital Isolators Overview

The SI8660AB-B-IS1R is a Skyworks Solutions digital isolator featuring six unidirectional channels with a data rate of 1 Mbps. It utilizes capacitive coupling for isolation and operates within a supply voltage range of 2.5 V to 5.5 V. The device provides an insulation voltage of 2.5 kVrms and supports an operating temperature range from -40 °C to +125 °C. Packaged in a 16-pin SOIC-Narrow (SOIC-16 NB) format, it offers a propagation delay of 35 ns and a power dissipation of 415 mW.

Digital Isolators Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Features six independent unidirectional signal channels for general-purpose applications
• Supports operation across extended industrial temperature ranges up to 125 °C

Digital Isolators Applications

• Industrial automation systems requiring circuit isolation
• Automotive electronics meeting AEC-Q100 standards
• General-purpose digital signal isolation interfaces

Digital Isolators Procurement Notes

Verify the specific suffix IS1R corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 1 Mbps data rate specification aligns with system timing requirements rather than higher-speed variants. Ensure compliance with RoHS directives and check for any regional regulatory certifications relevant to the deployment environment before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when six isolated channels are necessary for unidirectional signal transmission at moderate speeds. The 2.5 kVrms isolation rating suits applications with moderate voltage stress. Consider the SOIC-Narrow package dimensions for PCB layout constraints. Evaluate if the 35 ns propagation delay meets the specific timing margins of the target application compared to faster alternatives.

Digital Isolators Part Context

This part belongs to the Si86xx series of digital isolators manufactured by Skyworks Solutions. The series leverages CMOS SOI technology to provide robust isolation performance. The SI8660AB variant specifically denotes the channel count and isolation voltage class within the broader product family designed for replacing traditional optocouplers in modern electronic designs.
