SI88342ED-IS

Digital Isolators Overview

The SI88342ED-IS is a quad digital isolator from Skyworks Solutions featuring an integrated DC-DC converter. It provides four unidirectional channels with a data rate of 100 Mb/s and a propagation delay of 18 ns. The device offers 5000 Vrms isolation voltage using capacitive coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports a wide operating temperature range from -40°C to +125°C. The component is housed in a 24-SOIC package.

Digital Isolators Feature Summary

• Integrates a fully-featured secondary sensing feedback-controlled DC-DC converter for isolated power generation
• Provides high-speed signal isolation with 100 Mb/s data rate capability across four channels
• Delivers robust common-mode transient immunity through capacitive coupling technology

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Power electronics control circuits with isolated gate driving needs
• Medical equipment demanding high-voltage safety isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' corresponds to the tube packaging configuration, as other variants like 'ISR' indicate reel packaging. Confirm the component status is NRND (Not Recommended for New Designs) before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 24-SOIC package. Validate that the integrated DC-DC converter meets the target application's power requirements.

Digital Isolators Selection Notes

Select this component when a single-chip solution combining digital isolation and isolated power supply is required. The integrated DC-DC converter eliminates the need for external isolated power components. Consider the 5000 Vrms isolation rating for applications requiring high safety margins. Evaluate the 100 Mb/s data rate against system timing constraints. Check the -40°C to +125°C temperature range against environmental conditions.

Digital Isolators Part Context

This part belongs to the Si8834x family of digital isolators with integrated DC-DC converters. It shares architectural similarities with the SI88340ED-IS but differs in channel configuration and polarity. The series is designed for general-purpose isolation applications. Competing products typically require separate isolated power supplies, whereas this part integrates both functions.
