Overview
The SI88640ED-ISR is a unidirectional digital isolator from the Si8864x series, manufactured by Skyworks Solutions. It features four forward channels and zero reverse channels within a 24-pin SOIC-Wide package. The device supports data rates up to 100 Mb/s with a propagation delay of 18 ns. It operates on a supply voltage range of 3 V to 5.5 V and provides an insulation voltage of 5000 Vrms via capacitive coupling. The component includes an integrated DC-DC converter and meets AEC-Q100 automotive qualification standards.
Feature Summary
- Integrates a high-voltage DC-DC converter for isolated power generation
- Provides robust capacitive coupling isolation technology
- Includes shutdown functionality for power management
Applications
- Automotive electronic control units
- Industrial communication interfaces
- Medical equipment signal isolation
Procurement Notes
Verify the specific suffix 'ISR' indicates reel packaging rather than tube. Confirm the NRND status does not impact immediate procurement needs. Ensure compatibility with the si88xxxiso-kit development tools if evaluation is required. Check for moisture sensitivity level requirements during storage and handling.
Selection Notes
Select this part when four unidirectional channels are required alongside integrated isolation power. Compare against SI88640ED-IS for tube packaging differences. Consider SI88644ED-ISR if bidirectional or reverse channel capabilities are needed instead. Verify AEC-Q100 compliance is mandatory for the target application environment.
Part Context
This component belongs to the Si8864x family of high-speed digital isolators. It shares architectural similarities with SI88640ED-IS but differs in packaging format. The series is designed for applications requiring high common-mode transient immunity and reliable data transmission across isolation barriers.
Replacement Considerations
SI88640ED-IS is a direct functional substitute differing only in tube packaging. SI88644ED-ISR offers similar isolation but includes reverse channels.
