SI88243EC-AS

Digital Isolators Overview

The SI88243EC-AS is a general-purpose digital isolator from Skyworks Solutions, housed in a 20-SOIC package. It features four channels with one unidirectional forward channel and three reverse channels. The device supports data rates up to 100 Mb/s and offers an insulation voltage of 3750 Vrms. Operating parameters include a supply voltage range of 3 V to 5.5 V, a maximum propagation delay of 23 ns, and a common-mode transient immunity of 40 kV/µs. It functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four isolated channels for bidirectional signal transmission
• Provides high common-mode transient immunity for noise rejection
• Certified by UL, CSA, VDE, and CQC standards

Digital Isolators Applications

• Industrial automation systems
• Medical equipment isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm the exact packaging type and moisture sensitivity level. Ensure the required insulation voltage rating matches the application's safety requirements. Cross-reference the 20-SOIC footprint dimensions with PCB layout guidelines before finalizing procurement decisions.

Digital Isolators Selection Notes

Select this component when a four-channel isolator with integrated certification is required. Compare the 3750 Vrms insulation rating against system safety standards. Evaluate the 100 Mb/s data rate capability against signal timing requirements. Consider the 20-SOIC package size for board space constraints relative to other channel counts.

Digital Isolators Part Context

This part belongs to the Si8824x family of digital isolators designed for robust signal transmission across isolation barriers. The series emphasizes reliability in noisy environments through high CMTI ratings. The EC variant typically denotes specific qualification or performance tiers within the broader product line.

Digital Isolators Replacement Considerations

Check for SI88243ED-AS as a potential alternative within the same family. Verify pin compatibility and insulation voltage ratings before substitution.
