SI8452BA-A-IS1R

Overview

The SI8452BA-A-IS1R is a general-purpose digital isolator from Skyworks Solutions, featuring five channels with three forward and two reverse directions. It utilizes capacitive coupling technology to provide 1000 Vrms isolation voltage. The device supports data rates up to 150 Mb/s with a typical propagation delay of 6 ns. Operating on a supply voltage range of 2.7 V to 5.5 V, it includes a shutdown function and is housed in a 16-pin SOIC-Narrow package. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via capacitive coupling technology for signal transmission across isolated domains.
• Features unidirectional signal flow with configurable channel polarity for flexible system integration.
• Includes an integrated shutdown pin to minimize power consumption during inactive periods.

Applications

• Industrial automation systems requiring high-speed signal isolation
• Medical equipment needing reliable galvanic separation
• General-purpose digital communication interfaces

Procurement Notes

Verify the NRND (Not Recommended for New Designs) lifecycle status before procurement, as this indicates the component is no longer recommended for new designs. Confirm that the SOIC-Narrow-16 package and reel packaging meet your assembly requirements. Ensure compatibility with the specified 2.7 V to 5.5 V supply voltage range and check moisture sensitivity handling procedures upon receipt.

Selection Notes

Select this component when a 150 Mb/s data rate and 1000 Vrms isolation are required in a compact 16-pin package. It is suitable for applications needing three forward and two reverse channels with low propagation delay. Consider the NRND status if long-term production availability is critical, and verify thermal performance within the -40°C to +125°C operating range.

Part Context

This part belongs to the SI8452BA series of digital isolators from Skyworks Solutions. It shares the same core architecture and channel configuration as variants like the SI8452BA-B-IS1R but may differ in specific ordering suffixes or minor electrical characteristics. The series is designed for general-purpose isolation tasks requiring high reliability and speed.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on matching isolation voltage, data rate, channel count, and package dimensions.
