ISO7230CDWG4

Overview

The ISO7230CDWG4 is a high-speed, triple-channel digital isolator manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide electrical isolation between circuits. The device operates within a supply voltage range of 3.15 V to 5.5 V and supports data rates up to 25 Mb/s. It features an insulation voltage rating of 2500 Vrms and offers a typical propagation delay of 56 ns with a maximum rise time of 2 ns. The component is housed in a 16-pin SOIC package and is designed for operation across a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via capacitive coupling technology
• Supports high-speed data transmission at 25 Mb/s
• Features unidirectional signal path configuration

Applications

• Industrial automation systems requiring signal isolation
• Medical equipment needing patient isolation barriers
• Power metering applications for current sensing isolation

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards as per Texas Instruments documentation. Confirm the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the 2500 Vrms isolation rating meets your system's safety regulations. Check for moisture sensitivity levels if storage conditions are not controlled. Validate that the 3.15 V minimum supply voltage aligns with your power domain.

Selection Notes

Select this component when three independent unidirectional channels are required for high-speed communication. The 25 Mb/s data rate suits applications demanding faster throughput than standard isolators. The wide operating temperature range allows use in harsh industrial environments. Consider the SOIC-16 package for surface-mount assembly compatibility. Verify that the capacitive coupling isolation type fits your noise immunity requirements.

Part Context

This part belongs to the ISO7230A/C series of high-speed digital isolators from Texas Instruments. It is part of the broader interface IC category designed for robust signal transmission across isolated boundaries. The device complements other members of the family offering different channel counts or speed grades.

Replacement Considerations

ISO7230CDW is a compatible variant with identical electrical specifications but may differ in packaging format (tube vs. reel). Verify pinout compatibility before substitution. Ensure the replacement maintains the same 2500 Vrms isolation rating and 25 Mb/s data rate capabilities.
