SI88622BC-ASR

Overview

The SI88622BC-ASR is a Skyworks digital isolator featuring two unidirectional channels in a 20-SOIC package. It operates on a 3 V to 5.5 V supply with a maximum data rate of 100 Mb/s and insulation voltage of 5000 Vrms. The device exhibits 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 without a shutdown pin.

Feature Summary

• Provides galvanic isolation via capacitive coupling technology for signal transmission between isolated domains.
• Supports high-speed data communication up to 100 Mb/s with low propagation delay characteristics.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing reliable component separation
• General-purpose interface circuits demanding high common-mode transient immunity

Procurement Notes
