SI8663BD-B-ISR

Digital Isolators Overview

The SI8663BD-B-ISR 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 Mb/s 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 housed in a 16-pin SOIC-Wide package. The component is designed for unidirectional signal transmission across three forward and three reverse channels.

Digital Isolators Feature Summary

• Provides high-speed digital signal isolation using capacitive coupling technology
• Supports data transmission rates up to 150 Mb/s with low propagation delay
• Offers robust common-mode transient immunity for noise-sensitive environments
• Integrates six independent channels in a compact surface-mount package

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety isolation
• Power electronics control circuits
• Automotive electronic subsystems

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' against official Skyworks documentation to confirm tape-and-reel packaging and moisture sensitivity level. Ensure compatibility with design-in requirements regarding operating temperature ranges and pinout configurations before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when high channel count and moderate speed are required. Compare against the SI8663BD-B-IS variant to determine if reel packaging is necessary for assembly processes. Consider the 5 kVrms isolation rating relative to system safety standards and verify that the 150 Mb/s data rate meets application bandwidth needs.

Digital Isolators Part Context

This part belongs to the Si866x family of digital isolators, which are known for their reliability and performance in harsh environments. The SI8663 model specifically provides six channels, distinguishing it from lower-channel variants like the SI8662. The 'B' designation typically indicates a specific version or revision within the product line.

Digital Isolators Replacement Considerations

The SI8663BD-B-IS is a direct functional equivalent with identical electrical specifications but may differ in packaging format. Verify pin-to-pin compatibility and insulation ratings when substituting.
