SI88343BD-ASR is listed in the Isolators - Gate Drivers range at ChipApex. The manufacturer field lists Skyworks Solutions Inc.. Its product description is LINEAR IC. Review the specifications below when checking this part for your BOM.
The SI88343BD-ASR is a digital isolator from Skyworks Solutions, packaged in a 24-SOIC format. It features four channels with unidirectional polarity and supports data rates up to 100 Mb/s. The device operates within a supply voltage range of 3 V to 5.5 V and draws a typical operating current of 9.5 mA. It provides an insulation voltage of 5000 Vrms and exhibits a propagation delay of 18 ns. The component functions reliably across a temperature range of -40°C to +125°C.
Verify the specific suffix 'ASR' indicates tape and reel packaging when sourcing components. Confirm that the part number matches the active status listed by the manufacturer. Ensure compatibility with standard SOIC-24 footprints during integration. Check for RoHS compliance documentation as required by project specifications. Validate that the supplier provides official datasheets for technical reference.
Select this component for applications requiring unidirectional isolation with moderate speed requirements. Consider the 100 Mb/s data rate limit when designing communication links. Evaluate the 5000 Vrms insulation rating against system safety standards. Assess the 24-SOIC package dimensions for PCB layout constraints. Review the operating temperature range to ensure suitability for the intended environmental conditions.
This device belongs to the Si8834x series of digital isolators manufactured by Skyworks Solutions. The series utilizes proprietary CMOS technology to provide reliable isolation between circuits.
