SI8452AB-B-IS1R

Overview

The SI8452AB-B-IS1R is a five-channel digital isolator from Skyworks Solutions, utilizing capacitive coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and provides an insulation voltage of 2500 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 6 ns. It features three forward and two reverse channels in a narrow SOIC-16 package. The component functions reliably across temperatures from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via high-reliability capacitive coupling technology
• Supports unidirectional signal transmission across multiple independent channels
• Integrates shutdown functionality for power management optimization

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix IS1R indicates reel packaging configuration. Confirm RoHS compliance status through official documentation. Check current lifecycle status as NRND may impact long-term availability. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when high-speed data transmission requires robust isolation between circuit domains. The five-channel configuration reduces board space compared to single-channel alternatives. Verify that the 2500 Vrms insulation rating meets safety standards for the target application environment.

Part Context

This part belongs to the SI84xx series of digital isolators designed for general-purpose applications. It complements other Skyworks isolation products by offering a balance of speed and channel density. The series utilizes proprietary CMOS process technology for low power consumption.

Replacement Considerations

Consult official Skyworks substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications before implementation.
