SI8641EC-B-IS1R

Digital Isolators Overview

The SI8641EC-B-IS1R is a Skyworks Solutions digital isolator featuring four channels with three forward and one reverse configuration. It utilizes capacitive coupling technology to provide an isolation voltage of 3750 Vrms. The device supports data rates up to 150 Mb/s with a typical propagation delay of 13 ns. It operates within a supply voltage range of 2.5 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-SOIC format, it offers high common-mode transient immunity.

Digital Isolators Feature Summary

• Provides galvanic isolation via capacitive coupling technology for signal transmission between isolated domains.
• Features a unidirectional channel configuration with three inputs on the primary side and one output on the secondary side.
• Ensures signal integrity through high common-mode transient immunity capabilities.

Digital Isolators Applications

• Industrial automation systems requiring robust signal isolation
• Power electronics control circuits
• Medical equipment safety interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'EC' confirms the 3750 Vrms insulation rating and 150 Mb/s speed class. Confirm the 'IS1R' suffix indicates the reel packaging format. Ensure compatibility with the required operating temperature range and supply voltage specifications before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when high-voltage isolation of 3750 Vrms is required alongside high-speed data transmission. It is suitable for applications needing asymmetric channel configurations. Compare against lower voltage variants if system requirements allow for reduced isolation margins or cost optimization.

Digital Isolators Part Context

This part belongs to the Si864x family of digital isolators from Skyworks Solutions. The family is characterized by its use of silicon dioxide (SiO2) isolation technology, offering reliability comparable to optical isolators without the associated limitations. This specific model represents a high-performance variant within the series.

Digital Isolators Replacement Considerations

SI8641EC-B-IS1 is the tube-packaged equivalent of this reel-part. Other family members like SI8641BB-B-IS1R offer similar functionality but with different isolation ratings or speed classes.
