SI8441BB-D-ISR

Digital Isolators Overview

The SI8441BB-D-ISR is a Skyworks Solutions digital isolator featuring four channels with three forward and one reverse direction. It utilizes capacitive coupling technology to provide 2500 Vrms isolation voltage. The device supports data rates up to 150 Mb/s with a propagation delay of 6 ns. Operating on a supply voltage range of 2.7 V to 5.5 V, it includes a shutdown function. The component is housed in a 16-pin SOIC-Narrow package and operates within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation via capacitive coupling technology for signal integrity
• Integrates a dedicated shutdown pin for power management control
• Supports unidirectional data transmission across multiple channels
• Ensures high-speed digital communication with low propagation delay

Digital Isolators Applications

• General purpose digital isolation in industrial systems
• Isolation for microcontroller unit (MCU) interfaces
• Signal isolation in sensor networks
• Power supply feedback loop isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' confirms the SOIC-Narrow 16-pin package and reel packaging format. Confirm RoHS compliance status through official documentation. Check current lifecycle status as some variants may be marked as Not Recommended for New Designs. Ensure moisture sensitivity level handling procedures are followed during assembly.

Digital Isolators Selection Notes

Select this component when four isolated channels are required with mixed forward and reverse directions. Compare against SI8440BB series if only three forward channels are needed. Verify that the 2500 Vrms isolation rating meets system safety requirements. Ensure the 150 Mb/s data rate is sufficient for the application bandwidth needs.

Digital Isolators Part Context

This part belongs to the SI8441 family of digital isolators from Skyworks Solutions. It is designed for general-purpose applications requiring robust isolation between different voltage domains. The family offers various channel configurations and package options to suit diverse design constraints.

Digital Isolators Replacement Considerations

SI8441BB-D-IS serves as a tube-packaged alternative with identical electrical specifications but a wider SOIC package. SI8440BB-D-ISR provides a similar feature set with three forward channels instead of four.
