The Skyworks Solutions Inc. SI8421-A-IS is a 2-channel digital isolator designed for robust signal isolation in demanding applications. This component utilizes capacitive coupling technology to achieve 2500Vrms isolation, ensuring reliable performance in environments with high common-mode transients, boasting a minimum CMTI of 25kV/µs. Operating at data rates up to 1Mbps, the SI8421-A-IS offers low propagation delays of 75ns and minimal pulse width distortion of 30ns, with typical rise and fall times of 2ns. It operates across a supply voltage range of 2.375V to 5.5V and functions within an extended temperature range of -40°C to 125°C. The 8-SOIC package, with a standard 0.154" (3.90mm) width, is suitable for surface-mount assembly. This general-purpose isolator finds application in industrial automation, medical equipment, and power supply systems where signal integrity and safety are paramount.
