SI88340EC-AS

Digital Isolators Overview

The SI88340EC-AS is a general-purpose digital isolator manufactured by Skyworks Solutions Inc. It features four unidirectional channels with a data rate of 100 Mb/s and an isolation voltage of 3750 Vrms. The device operates within a supply voltage range of 3 V to 5.5 V, drawing a typical operating current of 10.8 mA. Key electrical parameters include a propagation delay of 18 ns, rise/fall times of 2.5 ns, and a common-mode transient immunity of 40 kV/µs. It is housed in a 24-SOIC package and supports an operating temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides robust galvanic isolation for high-speed digital signal transmission
• Utilizes capacitive coupling technology for reliable signal integrity
• Supports wide operating voltage ranges for flexible system integration

Digital Isolators Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics monitoring circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm it denotes the standard tube packaging variant rather than tape-and-reel configurations like 'ASR'. Ensure compatibility with 24-SOIC footprints during procurement planning. Cross-reference the exact part number with manufacturer datasheets to validate insulation ratings and channel counts before ordering.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is sufficient for the application design. Compare the 3750 Vrms rating against system safety requirements to ensure adequate margin. Evaluate the 100 Mb/s data rate against bandwidth needs. Consider the 24-SOIC package size for PCB layout constraints relative to alternative packages like QFN or SOIC-16 variants.

Digital Isolators Part Context

This part belongs to the Si8834x family of digital isolators from Skyworks Solutions. These devices are designed to replace traditional optocouplers in modern electronic designs. The family offers various channel counts and isolation voltages. The SI88340EC-AS specifically provides four channels with standard industrial isolation ratings.

Digital Isolators Replacement Considerations

Check Skyworks documentation for direct pin-compatible alternatives within the Si8834x series. Verify if higher isolation ratings such as those found in the SI88340ED-AS are required for specific safety standards. Ensure substitute parts maintain the same 24-SOIC footprint and unidirectional channel configuration.
