SI8642ET-ISR

Digital Isolators Overview

The SI8642ET-ISR is a Skyworks Solutions digital isolator featuring four unidirectional channels in a 16-pin SOIC-Wide package. It provides 5000 Vrms insulation voltage using capacitive coupling technology. The device supports data rates up to 150 Mb/s with a maximum propagation delay of 8 ns. Operating voltages range from 2.375 V to 5.5 V, and it functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides high-speed signal isolation via capacitive coupling for reliable data transmission
• Features four independent unidirectional channels for multi-signal separation
• Ensures safety compliance through robust 5000 Vrms insulation voltage rating

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient monitoring interfaces
• Power electronics control circuits for motor drives

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' indicates reel packaging when ordering. Confirm that the 5000 Vrms rating aligns with your system's isolation requirements. Check moisture sensitivity levels as indicated in datasheets. Ensure compatibility with standard SOIC-Wide-16 footprints during PCB design validation.

Digital Isolators Selection Notes

Select this component for applications demanding high common-mode transient immunity and low propagation delay. Compare against other Si864x variants if bidirectional isolation or different channel counts are needed. Verify power supply voltage ranges match your logic interface levels before integration into the circuit design.

Digital Isolators Part Context
