SI88322BD-ASR

Digital Isolators Overview

The SI88322BD-ASR is a Skyworks Solutions digital isolator featuring two unidirectional channels in a 20-pin SOIC package. It operates on a supply voltage between 3 V and 5.5 V with a typical quiescent current of 7.3 mA. The device supports data rates up to 100 Mb/s and provides an isolation voltage of 5000 Vrms. Key timing parameters include a propagation delay of 18 ns, rise/fall times of 2.5 ns, and pulse width distortion of 4.5 ns. It functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation for bidirectional signal transmission across separate power domains
• Integrates high-speed capacitive coupling technology for reliable data transfer
• Features unidirectional channel configuration for specific input-output signal routing

Digital Isolators Applications

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

Digital Isolators Procurement Notes

Verify the exact suffix ASR corresponds to reel packaging when ordering. Confirm RoHS compliance status through official datasheets. Check for obsolescence notices or lifecycle changes directly from Skyworks. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Digital Isolators Selection Notes

Select this component for applications requiring two-channel unidirectional isolation with high common-mode transient immunity. Compare against SI88322BD-AS if tube packaging is preferred over reels. Consider the SI88222 series for single-channel requirements or different pin counts. Verify thermal management needs given the operating temperature range and power dissipation characteristics.

Digital Isolators Part Context

This part belongs to the Si8832x family of digital isolators from Skyworks Solutions. These devices utilize proprietary iCoupler technology for signal isolation. The BD suffix indicates a wide-body SOIC package variant designed for higher creepage distances. The ASR suffix specifically denotes tape and reel packaging for automated surface-mount assembly processes.

Digital Isolators Replacement Considerations

SI88322BD-AS is a similar variant differing primarily in tube packaging instead of reels.
