SI88244BC-ASR

Digital Isolators Overview

The SI88244BC-ASR is a Skyworks Solutions digital isolator featuring four unidirectional channels in a 20-SOIC package. It supports data rates up to 100 Mb/s with a propagation delay of 18 ns and rise/fall times of 2.5 ns. The device operates on a supply voltage between 3 V and 5.5 V, providing an isolation voltage of 5000 Vrms. It functions within a temperature range of -40°C to +125°C and exhibits a common-mode transient immunity of 40 kV/µs.

Digital Isolators Feature Summary

• Provides galvanic isolation for high-speed digital signal transmission across noisy environments
• Integrates four independent unidirectional signal paths within a compact surface-mount package
• Utilizes capacitive coupling technology to ensure reliable operation without magnetic interference

Digital Isolators Applications

• Industrial automation control systems requiring robust signal isolation
• Medical equipment interfaces demanding high safety isolation standards
• Power electronics gate drive circuits for inverters and converters

Digital Isolators Procurement Notes

Verify the specific suffix 'ASR' to confirm reel packaging and 5000 Vrms isolation rating, as variants like 'IS' differ in insulation voltage and packaging. Confirm RoHS3 compliance status during sourcing. Check current availability as distribution may be limited. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Digital Isolators Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are needed with high CMTI. Compare against the SI88244BC-IS series if lower isolation voltage (3750 Vrms) is acceptable. Consider the SOIC-20 footprint constraints and verify that the 100 Mb/s data rate meets system timing requirements. Evaluate power consumption relative to other Skyworks isolators if efficiency is critical.

Digital Isolators Part Context
