ISO7230ADWR

Overview

The ISO7230ADWR is a triple digital isolator from Texas Instruments utilizing capacitive coupling technology. It provides three independent channels with unidirectional signal transmission at a data rate of 1 Mbps. The device offers an isolation voltage of 4000 Vpk and a common-mode transient immunity of 25 kV/µs. It operates within a supply voltage range of 3.15 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. Packaged in a 16-pin SOIC, it features a maximum propagation delay of 95 ns.

Feature Summary

• Provides galvanic isolation between two domains using robust capacitive coupling architecture
• Supports high-speed data transmission with low propagation delay for precise timing applications
• Ensures system reliability through high common-mode transient immunity against electrical noise

Applications

• Industrial communication interfaces requiring signal isolation
• Medical equipment safety circuits
• Power management systems with isolated feedback loops

Procurement Notes

Verify component authenticity due to the product's obsolete status. Confirm that the specific suffix 'R' denotes the reel packaging variant. Ensure compatibility with existing PCB footprints and design specifications before integration, as availability is limited.

Selection Notes

Select this component when three isolated channels are required for unidirectional data transfer at 1 Mbps. It is suitable for designs needing 4000 Vpk isolation strength and operation up to 125°C. Consider alternatives if bidirectional communication or higher data rates are necessary.

Part Context

This part belongs to the ISO7230A series of triple digital isolators. It shares the same pinout and functional characteristics as the non-reel version ISO7230ADW, differing only in packaging format. It serves as a general-purpose solution for replacing traditional optocouplers in modern interface designs.

Replacement Considerations

The ISO7731DWR is a recommended replacement from Texas Instruments. Verify that the substitute supports the required channel count and isolation voltage levels.
