Overview: The document outlines the technical specifications for the Silicon Laboratories Si8410/20/21 series digital isolators, which utilize an RF coupler for high-speed digital data transmission across an isolation barrier, ensuring low power consumption.

Features: These isolators support high-speed operations from DC to 150 Mbps with propagation delays under 10 ns. They function across a wide voltage range (2.375–5.5 V) and consume less than 12 mA per channel at 100 Mbps. They ensure precise timing with minimal pulse width distortion and excellent channel-channel matching, providing 2500 VRMS isolation and high transient immunity (>25 kV/µs).

Applications: Ideal for isolated switch mode supplies, isolated ADC/DAC, motor control, and power factor correction systems.

Safety and Regulatory Approvals: The devices are UL recognized for 2500 VRMS for 1 minute per UL1577, have CSA component acceptance, and conform to IEC 60747-5-2 standards.

Electrical Specifications: Detailed electrical characteristics are provided for various supply voltages (5 V, 3.3 V, and 2.5 V) and operating temperatures (-40 to 125 °C), including input/output voltage levels, supply current, and timing characteristics like maximum data rate, propagation delay, and pulse width distortion.

Layout Recommendations: Suggestions include supply bypassing, input/output characteristics, RF radiated emissions, and RF immunity considerations.

Regulatory Information: The Si84xx series complies with CSA, VDE, and UL standards, ensuring adherence to safety and insulation requirements.

Insulation and Safety-related Specifications: Details on minimum air gap, external tracking, internal gap, tracking resistance, and input-output resistance and capacitance are provided.
