SI88244EC-AS

Digital Isolators Overview

The SI88244EC-AS is a Skyworks Solutions digital isolator featuring four unidirectional channels in a 20-SOIC package. It operates on a supply voltage between 3 V and 5.5 V with a typical current consumption of 11 mA. The device supports data rates up to 100 Mb/s and provides an insulation voltage of 3750 Vrms. Key electrical parameters include a propagation delay of 18 ns, rise/fall times of 2.5 ns, and pulse width distortion of 4.5 ns. It functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four unidirectional signal paths for isolated data transmission
• Utilizes capacitive coupling technology for galvanic isolation
• Includes an integrated DC-DC converter for independent power domains
• Designed for high common-mode transient immunity applications

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive interfaces
• Automotive sensor interface circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' corresponds to the tube packaging configuration rather than reel formats. Confirm the 3750 Vrms insulation rating aligns with system safety requirements. Check RoHS compliance status and moisture sensitivity levels before assembly planning. Ensure the SOIC-20 footprint matches the target PCB layout constraints.

Digital Isolators Selection Notes

Select this component when four unidirectional channels are required with integrated power conversion. Compare against variants like SI88244EC-IS if higher 5000 Vrms isolation is needed. Consider the 100 Mb/s speed limit for high-frequency signaling needs. Evaluate the 20-SOIC package size against available board space.

Digital Isolators Part Context

This part belongs to the Si88244 family of general-purpose digital isolators from Skyworks Solutions. These devices combine capacitive isolation with on-chip DC-DC converters to provide robust signal separation in noisy environments. The EC-AS variant specifically denotes the 3750 Vrms insulation rating and tube packaging format within the broader product line.
