SI88342BD-IS

Digital Isolators Overview

The SI88342BD-IS is a dual-channel digital isolator from Skyworks Solutions, designed for robust signal transmission across isolation barriers. It features two independent channels with a typical propagation delay of 10 ns and a high common-mode transient immunity of 50 kV/μs. The device operates at a maximum data rate of 150 Mbps per channel and supports voltage levels up to 5 kVrms for reinforced insulation. Powered by a single supply ranging from 2.7 V to 5.5 V, it ensures reliable performance in noisy industrial environments while maintaining low power consumption.

Digital Isolators Feature Summary

• Dual-channel architecture provides independent signal isolation paths
• High common-mode transient immunity ensures signal integrity in noisy environments
• Supports wide operating temperature range for diverse application conditions

Digital Isolators Applications

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' indicates the extended temperature grade (-40°C to +125°C) against official Skyworks documentation. Confirm package type matches the SOIC-8 footprint. Ensure compliance with RoHS directives if required for your region. Cross-reference the datasheet revision date to guarantee accurate parameter values. Validate that the intended isolation voltage meets system safety standards.

Digital Isolators Selection Notes

Choose this component when dual-channel isolation is necessary within a compact form factor. Consider its 5 kVrms rating for applications demanding reinforced insulation between high-voltage and low-voltage domains. Evaluate the 150 Mbps speed capability against your system's communication requirements. Assess power consumption needs relative to other available isolators. Verify thermal performance specifications for your specific enclosure constraints.
