SI8635ET-IS2R

Digital Isolators Overview

The SI8635ET-IS2R is a general-purpose digital isolator from the Skyworks si863x series, housed in a 16-SOIC package. It features three unidirectional channels with a data rate of 150 Mb/s and an insulation voltage of 5000 Vrms. The device supports a supply voltage range of 2.5 V to 5.5 V and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a common-mode transient immunity (CMTI) of 60 kV/µs.

Digital Isolators Feature Summary

• Capacitive coupling isolation technology for signal transmission
• High common-mode transient immunity capability
• Unidirectional channel configuration
• Automotive-grade surge protection rating

Digital Isolators Applications

Digital Isolators Procurement Notes

Verify the specific suffix 'IS2R' against official Skyworks documentation to confirm the reel packaging format and any distinct qualification status compared to tube variants. Ensure the component matches the required 16-SOIC footprint and pinout specifications for your design integration.

Digital Isolators Selection Notes

Select this component when unidirectional isolation with 150 Mb/s speed is required. The 60 kV/µs CMTI makes it suitable for noisy environments. Confirm that the 5000 Vrms insulation rating meets system safety standards and that the SOIC-16 package fits the PCB layout constraints.

Digital Isolators Part Context

This part belongs to the si863x family of digital isolators by Skyworks Solutions. These devices utilize capacitive coupling technology to provide robust isolation between circuit domains while maintaining low power consumption and high reliability for industrial and automotive applications.

Digital Isolators Replacement Considerations

Check Skyworks datasheets for compatible parts within the si863x series, such as SI8635ET-IS2 or SI8635ET-ISR, ensuring identical channel count, speed, and package dimensions before substitution.
