SI88322ED-ISR

Digital Isolators Overview

The SI88322ED-ISR is a Skyworks Solutions digital isolator featuring two unidirectional channels with an integrated DC-DC converter. It provides 5000 Vrms isolation using capacitive coupling technology. The device supports data rates up to 100 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 18 ns, typical rise and fall times of 2.5 ns, and a minimum common-mode transient immunity of 40 kV/µs. It functions reliably across a temperature range of -40°C to +125°C and is housed in a 20-SOIC package.

Digital Isolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and AEC-Q100 automotive qualification if required for specific applications. Check datasheet revisions for updates on electrical characteristics. Ensure storage conditions meet moisture sensitivity level requirements before assembly. Validate pinout compatibility with target PCB footprint during procurement planning.

Digital Isolators Selection Notes

Select this component when dual-channel isolation with integrated power conversion is necessary. Consider the 20-SOIC package dimensions for board space constraints. Evaluate the 100 Mb/s data rate against system timing requirements. Assess thermal performance within the specified operating temperature range. Compare alternative SKUs like SI88322EC-ISR for potential functional differences or availability issues.
