SI88344ED-ASR

Digital Isolators Overview

The SI88344ED-ASR is a Skyworks Solutions digital isolator featuring four unidirectional channels in a 24-SOIC package. It operates on a 3 V to 5.5 V supply with a typical current of 11 mA. The device supports data rates up to 100 Mb/s and provides 5000 Vrms isolation voltage. Key electrical parameters include an 18 ns propagation delay, 2.5 ns rise/fall times, and 4.5 ns pulse width distortion. It functions within a temperature range of -40°C to +125°C without a shutdown pin.

Digital Isolators Feature Summary

• Provides high-speed digital signal transmission via capacitive coupling technology
• Integrates four independent unidirectional signal paths for complex interface isolation
• Ensures robust noise immunity through specified common-mode transient rejection capabilities

Digital Isolators Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal processing interfaces
• Power electronics gate drive circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'ASR' against official Skyworks documentation to confirm the reel packaging configuration and moisture sensitivity level. Ensure compatibility with standard SOIC-24 footprints during PCB layout. Confirm that the unidirectional channel configuration meets the system's signal flow requirements before finalizing procurement.

Digital Isolators Selection Notes

Select this component when four isolated unidirectional channels are required without integrated power conversion. Compare against the SI88344ED-ISR variant if bidirectional communication or integrated DC-DC functionality is necessary. Verify that the 100 Mb/s data rate aligns with the application's timing constraints and that the 5000 Vrms isolation rating satisfies safety standards.

Digital Isolators Part Context

This part belongs to the Si88x4x family of general-purpose digital isolators from Skyworks Solutions. These devices utilize proprietary iCoupler chip-scale transformer technology to provide reliable isolation in compact surface-mount packages. The series is designed for applications demanding high reliability and low power consumption in noisy environments.
