SI88341ED-IS

Digital Isolators Overview

The SI88341ED-IS is a general-purpose digital isolator from Skyworks Solutions, featuring integrated DC-DC converter capabilities. It provides galvanic isolation with a rated insulation voltage of 5000 Vrms using capacitive coupling technology. The device supports a data rate of 100 Mb/s and includes four channels configured as three forward and one reverse channel. 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 operates within a supply voltage range of 3 V to 5.5 V and functions across an industrial temperature range of -40°C to +125°C. The component is housed in a 24-SOIC package.

Digital Isolators Procurement Notes

Verify the specific suffix 'ED' to confirm the 24-SOIC wide package and unidirectional channel configuration. Confirm RoHS compliance status through official documentation. Check for Not Recommended for New Design (NRND) status implications on long-term availability. Ensure compatibility with required isolation voltage ratings for the target application safety standards before procurement.

Digital Isolators Selection Notes

Select this component when a combination of digital isolation and integrated power conversion is required in a single package. The 4-channel configuration suits applications needing multiple isolated signal paths. Verify that the 5000 Vrms insulation rating meets system safety requirements. Consider the 100 Mb/s data rate limit for high-speed interface compatibility. Evaluate thermal performance given the 2.27 W power dissipation capability.
