SI8660BD-B-ISR

Digital Isolators Overview

The SI8660BD-B-ISR is a six-channel digital isolator from the Si866x series, manufactured by Skyworks Solutions. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 5000 Vrms. The device supports a data rate of 150 Mb/s and features a 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 SOIC-Wide-16 package and functions unidirectionally across all channels.

Digital Isolators Feature Summary

• Power monitoring systems
• Motor drive control circuits

Digital Isolators Procurement Notes

Verify that the specific suffix B-ISR corresponds to the required tape and reel packaging configuration. Confirm that the SOIC-Wide-16 footprint matches the target PCB layout constraints. Ensure the AEC-Q100 qualification aligns with the intended automotive application requirements. Check moisture sensitivity levels for proper storage and handling procedures during assembly.

Digital Isolators Selection Notes

Select this component when six isolated channels are required for unidirectional signal transmission. Consider the 5000 Vrms isolation rating for high-noise environments. Evaluate the 150 Mb/s data rate against system timing requirements. Verify compatibility with the 2.375 V to 5.5 V operating voltage range.

Digital Isolators Part Context

This part belongs to the Si866x family of digital isolators designed for robust signal integrity. It replaces traditional optocouplers in many applications due to smaller size and lower power consumption. The wide-body SOIC package facilitates easier surface-mount assembly compared to narrow variants.

Digital Isolators Replacement Considerations

SI8660BC-B-IS1R offers similar functionality with 3750 Vrms isolation in a narrow SOIC package.
