ISO7221MDRG4

Overview

The ISO7221MDRG4 is a dual-channel digital isolator from Texas Instruments utilizing capacitive coupling technology. It features two unidirectional channels with a data rate of 150 Mbps and an isolation voltage of 2500 Vrms. The device operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range of -40°C to +125°C. Packaged in an 8-SOIC format, it provides general-purpose signal isolation for industrial applications.

Feature Summary

• Capacitive coupling architecture for high-speed signal transmission
• Dual unidirectional channel configuration
• Wide operating temperature range support

Applications

• Industrial process control systems
• Isolated communication interfaces
• General-purpose circuit isolation

Procurement Notes

Verify the specific suffix 'MDRG4' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 8-SOIC package. Cross-reference datasheet revisions to validate electrical parameters before integration into final designs.

Selection Notes

Select this component when a dual-channel solution with 150 Mbps throughput is required. It is suitable for applications needing 2500 Vrms isolation without integrated power supplies. Consider thermal management requirements for the SOIC package in dense layouts.

Part Context

This part belongs to the ISO722x family of digital isolators. It shares architectural similarities with other variants like ISO7221MDR but includes specific packaging and reel configurations indicated by the suffix. It serves as a robust alternative to magnetic or optical isolation technologies in space-constrained designs.

Replacement Considerations

ISO7221MDR is a compatible variant within the same product family offering identical electrical characteristics.
