SI88241BD-IS

Digital Isolators Overview

The SI88241BD-IS is a general-purpose digital isolator from Skyworks Solutions, featuring four channels with three forward and one reverse configuration. It utilizes capacitive coupling technology to provide an insulation voltage of 5000 Vrms and supports data rates up to 100 Mb/s. The device operates within a supply voltage range of 3 V to 5.5 V and exhibits a propagation delay of 18 ns. It offers a common-mode transient immunity of 40 kV/µs and functions across a temperature range of -40°C to +125°C. Packaged in a 20-SOIC (0.295 inch width) format, it includes shutdown functionality.

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as indicated in official documentation. Check the lifecycle status, as this component may be marked as Not Recommended for New Designs (NRND). Ensure that the 20-SOIC footprint matches your PCB design requirements before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when a four-channel isolator with asymmetric forward/reverse channel distribution is required. The 5000 Vrms insulation rating suits applications demanding robust safety barriers. Consider the 100 Mb/s data rate limit for high-speed interface needs. Evaluate the 20-SOIC package size constraints relative to available board space. Verify thermal dissipation capabilities within the specified operating temperature range.

Digital Isolators Part Context

This part belongs to the Si8824x series of digital isolators from Skyworks Solutions. It shares the family's core capacitive isolation technology but differs in channel count and configuration compared to variants like the SI88240 or SI88243. The 'BD' indicates the wide SOIC package, while 'ISR' or 'IS' denotes specific tape-and-reel or tube packaging options.
