SI88244BC-IS

Digital Isolators Overview

The SI88244BC-IS is a Skyworks Solutions digital isolator featuring four unidirectional channels with a data rate of 100 Mb/s. It provides 3750 Vrms isolation voltage using capacitive coupling technology. The device operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 18 ns, rise/fall times of 2.5 ns, and a common-mode transient immunity of 40 kV/µs. It is housed in a 20-SOIC package.

Digital Isolators Feature Summary

• Integrates four independent unidirectional signal paths for multi-channel isolation
• Utilizes silicon dioxide (SiO2) capacitive coupling for high reliability
• Supports wide operating temperature range suitable for industrial environments

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Programmable logic controller (PLC) input/output modules
• Inverter and motor drive control circuits
• Power supply feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' corresponds to the tube packaging configuration rather than reel variants like 'ISR'. Confirm RoHS compliance status and moisture sensitivity level requirements during storage handling. Ensure the 20-SOIC footprint matches the target PCB design constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when four isolated channels are required without integrated power conversion. Compare against Si88244BC-AS if higher 5000 Vrms isolation is needed. Consider Si88244BC-ISR only if reel packaging is strictly required for automated assembly processes. Verify channel directionality meets system signal flow requirements.

Digital Isolators Part Context

This part belongs to the Si88xx ISOvolt family of digital isolators. It replaces legacy optocoupler solutions by offering smaller size and lower power consumption. The device integrates high-speed CMOS technology to provide robust signal transmission across isolation barriers while maintaining safety certification standards for industrial equipment.

Digital Isolators Replacement Considerations

SI88244BC-AS offers equivalent functionality with increased 5000 Vrms isolation rating. SI88244BC-ISR provides identical electrical specifications but utilizes reel packaging instead of tubes. Both are parameter-equivalent alternatives within the same manufacturer portfolio.
