SI8640ED-B-YSR

Digital Isolators Overview

The SI8640ED-B-YSR is a Skyworks Solutions digital isolator featuring four unidirectional channels in a 16-SOIC package. It operates on a supply voltage range of 2.375 V to 5.5 V with a typical quiescent current of 17.5 mA. The device provides an insulation voltage of 5000 Vrms and supports data rates up to 150 Mb/s. Key timing parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a pulse width of 5 ns. It functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Utilizes capacitive coupling technology for signal isolation between circuits.
• Provides high common-mode transient immunity of 35 kV/µs.
• Supports general-purpose digital signal transmission across isolated boundaries.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Power management circuits with high-voltage separation needs
• Medical equipment demanding safe patient isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'YSR' corresponds to the tape-and-reel packaging format rather than tube packaging. Confirm that the 'ED' designation aligns with the required insulation voltage rating of 5000 Vrms for your application safety standards. Ensure the operating temperature range meets environmental requirements.

Digital Isolators Selection Notes

Select this component when four independent unidirectional channels are required with high-speed performance up to 150 Mb/s. Consider the 17.5 mA power consumption against lower-power alternatives if energy efficiency is critical. The SOIC-16 package offers a balance between pin count and board space constraints.

Digital Isolators Part Context

This part belongs to the Si864x family of digital isolators from Skyworks Solutions. It is designed as a robust alternative to traditional optocouplers, offering faster switching speeds and smaller form factors while maintaining high reliability in electrically noisy environments.

Digital Isolators Replacement Considerations

Check for direct substitutes within the Si864x series such as SI8640ED-B-IS1 or SI8640BT-ASR, ensuring package compatibility and insulation ratings match. Verify that any replacement maintains the same channel configuration and speed specifications.
