ISO7231MDW

Overview

The ISO7231MDW is a triple-channel digital isolator manufactured by Texas Instruments, housed in a 16-pin SOIC package. It supports data rates up to 150Mbps with a propagation delay of 34ns. The device provides an isolation voltage of 4000Vrms and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for three independent signal channels using capacitive coupling technology.
• Supports high-speed data transmission at rates up to 150Mbps with low propagation delay.
• Features bidirectional signal capability for flexible circuit design integration.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing enhanced electrical safety barriers
• Power metering circuits for accurate measurement isolation

Procurement Notes

Verify the specific ordering suffix (e.g., G4) against the datasheet to ensure compliance with RoHS standards and material declarations. Confirm that the package type matches the required PCB footprint. Check current availability status as this component may be subject to discontinuation or limited stock conditions.

Selection Notes

Select this component when high-speed data integrity is critical alongside strong isolation requirements. Ensure the system voltage levels are compatible with the specified input and output thresholds. Consider thermal management capabilities given the wide operating temperature range and power consumption characteristics.

Part Context

This part belongs to the ISO7231 family of high-speed digital isolators from Texas Instruments. It shares architectural similarities with other members like the ISO7230 series but offers distinct channel configurations and speed ratings tailored for specific interface needs.

Replacement Considerations

ISO7231MDWG4 serves as a verified lead-free alternative within the same product line. Verify pin compatibility and electrical specifications before substitution.
