SI88320EC-IS

Digital Isolators Overview

The SI88320EC-IS is a digital isolator and integrated DC-DC converter manufactured by Skyworks Solutions. It features two unidirectional channels with a data rate of 100 Mb/s and an insulation voltage of 3750 Vrms using capacitive coupling. The device operates on a supply voltage between 3 V and 5.5 V, consuming 9.5 mA of working power current. Key electrical parameters include a propagation delay of 18 ns, rise and fall times of 2.5 ns, and a pulse width of 10 ns. It supports a shutdown function and functions within a temperature range of -40°C to +125°C. Packaged in a SOIC-20 format, it holds AEC-Q100 qualification.

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' against the manufacturer's official datasheet to confirm the package type and tape-and-reel or tube configuration. Ensure the component meets AEC-Q100 automotive standards if required for the target application. Cross-reference the ordering part number with the manufacturer's latest documentation to avoid discrepancies in packaging quantity or moisture sensitivity levels.

Digital Isolators Selection Notes

Select this component when a combined digital isolator and isolated power source is needed to reduce system complexity. The 3750 Vrms insulation rating suits applications requiring reinforced safety isolation. Consider the 100 Mb/s data rate and 18 ns delay for high-speed signal transmission needs. The wide operating temperature range supports harsh industrial environments.

Digital Isolators Part Context

This part belongs to the Si88xx ISOvolt series, which combines digital isolation with integrated DC-DC converters. This family replaces traditional optocouplers by offering smaller size, lower power consumption, and higher reliability. The SI88320EC-IS specifically targets designs needing dual-channel isolation with onboard power conversion capabilities.

Digital Isolators Replacement Considerations

Consult the manufacturer's official cross-reference guide for verified substitutes. Generic equivalents may not match the integrated DC-DC converter specifications or the exact insulation voltage ratings.
