SI8452BA-A-IS1

Overview

The SI8452BA-A-IS1 is a general-purpose digital isolator from Skyworks Solutions, featuring five channels with three forward and two reverse paths. It operates on a single supply voltage between 2.7 V and 5.5 V, delivering a data rate of 150 Mb/s. The device provides 1000 Vrms isolation via capacitive coupling and supports a typical common-mode transient immunity of 25 kV/µs. It includes a shutdown function and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for circuits operating at different voltage levels
• Integrates five independent signal channels in a compact package
• Features low propagation delay for high-speed data transmission
• Includes a dedicated shutdown pin for power management

Applications

• General-purpose digital isolation
• Industrial automation systems
• Power supply control circuits

Procurement Notes

Verify the specific suffix IS1 against official Skyworks documentation to confirm the tape-and-reel packaging configuration. Confirm RoHS compliance status through the manufacturer's current datasheet. Note that this component may be classified as Not Recommended for New Designs (NRND); validate long-term availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when five isolated channels are required within a single package. Ensure the application voltage does not exceed the 5.5 V maximum rating. Verify that the system requires unidirectional signal flow compatible with the specified channel configuration. Check thermal dissipation requirements against the 415 mW power dissipation limit.

Part Context

This part belongs to the SI8452BA series of digital isolators. It utilizes Skyworks' proprietary capacitive coupling technology to achieve isolation without magnetic components. The SOIC-16 narrow package allows for standard surface-mount assembly processes.

Replacement Considerations

The SI8452BA-B-IS1 is a documented variant within the same family. Verify if the B suffix indicates a functional difference or merely a manufacturing lot variation by consulting the official Skyworks comparison guide.
