ISO7710FQDRQ1

Overview

The ISO7710FQDRQ1 is a high-speed, robust EMC reinforced single-channel digital isolator from Texas Instruments. It operates with a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 100 Mb/s. The device features an insulation voltage of 3000 Vrms and a common-mode transient immunity (CMTI) of 85 kV/µs. It has a typical propagation delay of 11 ns and operates within a temperature range of -40°C to 125°C. Packaged in an 8-SOIC surface-mount package, it is designed for automotive applications requiring reliable signal isolation.

Feature Summary

• Robust electromagnetic compatibility performance suitable for harsh environments
• High common-mode transient immunity ensuring signal integrity
• Single-channel design for efficient space-constrained layouts

Applications

• Automotive electronic control units
• Industrial communication interfaces
• Motor drive systems

Procurement Notes

Verify the complete part number including suffixes such as 'R1' for reel packaging when ordering. Confirm that the specific variant matches your system's voltage and isolation requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides valid traceability documentation for automotive-grade components.

Selection Notes

Select this component when a single isolated channel with high speed and robust EMC characteristics is needed. It is suitable for applications requiring 3000 Vrms isolation between circuits. Consider the 8-SOIC package size for board space constraints. Verify that the 100 Mb/s data rate meets the system's communication speed requirements.

Part Context

This device belongs to the ISO7710-Q1 family of digital isolators. It is specifically engineered for automotive applications meeting AEC-Q100 standards. The series offers various channel configurations and isolation levels to suit different system architectures.

Replacement Considerations

Check for direct pin-to-pin replacements within the same manufacturer's portfolio. Verify that any substitute maintains the same isolation voltage and CMTI ratings. Ensure the alternative component supports the required data rate and operating temperature range.
