SI8641ED-AS

Digital Isolators Overview

The SI8641ED-AS is a general-purpose digital isolator from the Si864x series, manufactured by Skyworks Solutions Inc. It features four unidirectional channels with three forward and one reverse path, operating at data rates up to 150 Mbps. The device provides an insulation voltage of 5000 Vrms and utilizes capacitive coupling technology. It supports a wide supply voltage range from 2.375 V to 5.5 V and operates within a temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC-Wide format, it offers a propagation delay of 8 ns and high common-mode transient immunity.

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm package type and tape/reel specifications. Ensure compatibility with required insulation standards and thermal management needs for the target application environment.

Digital Isolators Selection Notes

Select this component when high-speed unidirectional isolation is required with a wide supply voltage range. Consider the 16-pin SOIC-Wide package for PCB layout constraints. Verify that the 5000 Vrms insulation rating meets system safety requirements.

Digital Isolators Part Context

Part of the Si864x family of digital isolators, designed for replacing traditional optocouplers in space-constrained designs. Offers superior performance in speed, power consumption, and reliability compared to legacy technologies.

Digital Isolators Replacement Considerations

Check pinout compatibility with existing optocoupler designs. Verify that the capacitive isolation architecture does not introduce unwanted noise coupling in sensitive analog circuits.
