SI88344ED-IS

Digital Isolators Overview

The SI88344ED-IS is a general-purpose digital isolator from Skyworks Solutions, featuring four unidirectional channels with an integrated DC-DC converter. It utilizes capacitive coupling technology to provide galvanic isolation between circuits operating at different voltage levels. The device supports data rates up to 100 Mb/s and offers an insulation voltage of 5000 Vrms. It operates within a supply voltage range of 3 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a 24-SOIC (0.295", 7.50mm wide) format, it includes a shutdown feature for power management.

Digital Isolators Feature Summary

• Integrates a high-voltage DC-DC converter to enable isolated power delivery without external components.
• Provides robust galvanic isolation via capacitive coupling technology for noise immunity.
• Includes a dedicated shutdown pin to minimize power consumption during inactive periods.

Digital Isolators Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing high-voltage safety compliance
• Power electronics interfaces for motor control and inverters

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' against official Skyworks documentation to confirm package type and tape/reel configuration. Check current lifecycle status as some variants may be marked Not Recommended for New Designs. Ensure compatibility with moisture sensitivity level requirements during assembly processing.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional channels. Consider the integrated DC-DC converter if isolated power generation is needed on the secondary side. Evaluate the 24-pin SOIC footprint against available PCB space constraints.

Digital Isolators Part Context

This part belongs to the Si88x4x series of digital isolators from Skyworks Solutions. It shares architectural similarities with other members like the SI88340 and SI88341 but differs in channel directionality and internal DC-DC converter integration. The series is designed for high-reliability applications demanding strict isolation standards.
