SI88241ED-ASR

Digital Isolators Overview

The SI88241ED-ASR is a Skyworks Solutions digital isolator featuring four unidirectional channels and an integrated DC-DC converter. It provides 5000 Vrms isolation via capacitive coupling with a data rate of 100 Mb/s. The device operates on a 3 V to 5.5 V supply, exhibits 18 ns propagation delay, and supports a maximum CMTI of 40 kV/µs. Packaged in a 20-SOIC (7.50 mm wide) reel, it functions within a -40°C to +125°C temperature range.

Digital Isolators Feature Summary

• Integrates a high-efficiency DC-DC converter for isolated power generation
• Provides robust 5000 Vrms insulation barrier using capacitive coupling technology
• Delivers high-speed signal transmission at 100 Mb/s with low latency

Digital Isolators Applications

• Industrial automation control systems
• Power electronics gate drive interfaces
• Medical equipment signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'ASR' confirms the tape-and-reel packaging format and SOIC-20 footprint. Ensure the design accounts for the integrated DC-DC converter requirements, including external decoupling components as specified in the datasheet. Confirm that the 5000 Vrms isolation rating meets the safety standards required for the target application environment.

Digital Isolators Selection Notes

Select this component when a single package solution combining signal isolation and isolated power delivery is required. The 4-channel configuration suits applications needing multiple isolated data lines alongside power conversion. Consider the 100 Mb/s speed limit and 18 ns delay for timing-critical designs requiring high bandwidth across the isolation barrier.

Digital Isolators Part Context

This part belongs to the Si88x4x family of digital isolators from Skyworks Solutions. It combines standard digital isolation capabilities with an onboard switching regulator, reducing external component count compared to discrete solutions. The series is designed for high-reliability applications demanding strict galvanic separation between circuit domains.
