ISO7310FCQDRQ1

Overview

The ISO7310FCQDRQ1 is an automotive-grade, single-channel digital isolator from Texas Instruments. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 25Mbps. The device provides 3000Vrms isolation capability with a common-mode transient immunity (CMTI) of 25kV/µs. It is housed in an 8-pin SOIC (D) package and functions reliably across an extended temperature range of -40°C to 125°C.

Feature Summary

• Robust electromagnetic compatibility performance for demanding automotive environments
• Low power consumption design suitable for energy-efficient applications
• Single-channel configuration providing isolated signal transmission

Applications

• Profibus communication interfaces
• Automotive electronic control units
• Industrial automation systems requiring galvanic isolation

Procurement Notes

Verify the specific ordering suffix matches the required package and temperature grade. Confirm that the component meets AEC-Q100 qualification standards for automotive reliability. Ensure the datasheet version aligns with the manufacturing date code to guarantee parameter consistency.

Selection Notes

Select this component when a single isolated channel with high CMTI is required. It is appropriate for applications needing 3000Vrms isolation between circuits. Consider the 25Mbps speed limit and 3-5.5V operating range during system design.

Part Context

This part belongs to the ISO7310-Q1 family of robust, low-power digital isolators designed for automotive use. It offers a simplified single-channel solution compared to multi-channel variants. The device integrates silicon dioxide insulation technology for long-term stability.

Replacement Considerations

Direct substitutes include other single-channel automotive digital isolators with similar isolation ratings and pinouts. Verify functional equivalence regarding CMTI and propagation delay before substitution.
