SI8660ED-B-IS

Digital Isolators Overview

The SI8660ED-B-IS is a six-channel digital isolator from the Si866x series, manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 5000 Vrms. The device supports data rates up to 150 Mbps and features a typical propagation delay of 8 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and is qualified under AEC-Q100 standards for automotive applications. The component is housed in a 16-pin Wide SOIC package and functions within an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides high-voltage galvanic isolation between circuits using robust capacitive coupling architecture.
• Supports unidirectional signal transmission across six independent channels for general-purpose digital interfaces.
• Ensures signal integrity in noisy environments through a common-mode transient immunity rating of 35 kV/µs.

Digital Isolators Applications

• Automotive electronic control units requiring AEC-Q100 qualified isolation
• Industrial automation systems utilizing isolated communication buses
• Medical equipment needing reinforced safety isolation barriers

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' confirms the 16-Wide SOIC package configuration distinct from other variants. Confirm AEC-Q100 qualification status if deploying in automotive contexts. Ensure compatibility with the required 2.375 V to 5.5 V supply rails. Check moisture sensitivity level handling requirements during assembly. Validate that the 5000 Vrms isolation rating meets the specific safety standards of the target application.

Digital Isolators Selection Notes

Select this component when six isolated channels are required for unidirectional data transfer. Choose this part over lower-rated isolators if 5000 Vrms insulation is mandatory for safety compliance. Consider the 150 Mbps speed limit when designing high-frequency digital interfaces. Evaluate the Wide SOIC footprint against available PCB space constraints. Verify thermal dissipation capabilities given the 415 mW power dissipation specification.
