SI8631BB-B-IS

Digital Isolators Overview

The SI8631BB-B-IS is a Skyworks Solutions digital isolator featuring three independent channels with unidirectional signal paths. It utilizes capacitive coupling technology to provide an insulation voltage of 2500 Vrms. The device supports data rates up to 150 Mbps and operates within a supply voltage range of 2.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8 ns, rise and fall times of 4 ns, and a pulse width distortion of 4.5 ns. It functions reliably across a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC-Wide package.

Digital Isolators Feature Summary

• Capacitive coupling isolation architecture for high-speed signal transmission
• Unidirectional channel configuration supporting general-purpose applications
• Wide operating supply voltage range accommodating various logic levels

Digital Isolators Applications

• Industrial automation control systems
• Power management circuit isolation
• General-purpose digital communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'B-IS' against official Skyworks documentation to confirm the SOIC-Wide-16 package variant. Ensure that the required insulation voltage rating of 2500 Vrms aligns with system safety standards. Confirm that the unidirectional channel topology matches the intended signal flow requirements before finalizing component selection.

Digital Isolators Selection Notes

Select this component when a 2500 Vrms isolation barrier is sufficient for the application's safety requirements. The 150 Mbps data rate capability makes it suitable for moderate-speed digital interfaces. Consider the 16-pin wide SOIC footprint for PCB layout compatibility. Verify that the 8 ns propagation delay meets the timing constraints of the connected logic circuits.
