SI88222ED-AS

Digital Isolators Overview

The SI88222ED-AS is a two-channel digital isolator from Skyworks Solutions, housed in a 16-SOIC package. It supports data rates up to 100 Mb/s with an isolation voltage of 5000 Vrms and a common-mode transient immunity of 40 kV/µs. The device operates on a supply voltage between 3 V and 5.5 V, drawing a typical operating current of 7.3 mA. Propagation delays are specified at 23 ns maximum, with rise and fall times of 2.5 ns. Pulse width distortion is limited to 4.5 ns. It functions within a temperature range of -40°C to +125°C and lacks a shutdown feature.

Digital Isolators Feature Summary

• Provides galvanic isolation for bidirectional digital signal transmission across two independent channels.
• Utilizes capacitive coupling technology to achieve high common-mode transient immunity.
• Designed for robust performance in harsh electrical environments with wide operating temperature ranges.

Digital Isolators Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits demanding high-voltage isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm the tube packaging configuration. Ensure compatibility with 16-SOIC footprints during PCB layout. Confirm that the unidirectional channel configuration meets system requirements, as this variant specifies zero forward channels and two reverse channels. Cross-reference moisture sensitivity levels for proper storage handling.

Digital Isolators Selection Notes

Select this component when a dual-channel isolator with 5000 Vrms isolation is required without integrated power conversion. Compare propagation delay specifications against timing constraints of the target interface protocol. Evaluate the 16-SOIC package dimensions against available board space. Consider the absence of a shutdown pin if power management features are necessary for the application design.

Digital Isolators Part Context

This part belongs to the Si8822x series of digital isolators, which are designed for general-purpose isolation applications. The series emphasizes high reliability and low power consumption. The SI88222ED-AS specifically targets applications needing two isolated channels with standard speed capabilities. It complements other variants in the family that may offer different channel counts or integrated DC-DC converters.

Digital Isolators Replacement Considerations

SI88222EC-ISR is listed as a similar alternative by distributors. Verify functional equivalence regarding channel directionality and package type before substitution. Check datasheet updates for any changes in electrical characteristics or pinout definitions between the AS and ISR suffixes.
