ISO7320CQDRQ1

Overview

The ISO7320CQDRQ1 is an automotive-grade, low-power, dual-channel digital isolator from Texas Instruments. It features a 2/0 channel configuration with integrated noise filters for harsh industrial environments. Key electrical parameters include a minimum supply voltage of 3 V, maximum supply voltage of 5.5 V, operating supply current of 4.9 mA, propagation delay time of 32 ns, data rate of 25 Mb/s, and isolation voltage of 3000 Vrms using capacitive coupling. The device operates within a temperature range starting at -40 C.

Feature Summary

• Integrated noise filters designed to handle short noise pulses in harsh industrial environments
• Automotive qualification compliant with AEC-Q100 standards
• Low-power consumption characteristics suitable for energy-efficient applications

Applications

• Automotive electronic control units requiring robust signal isolation
• Industrial systems exposed to high electromagnetic interference
• Safety-critical circuits needing certified galvanic isolation

Procurement Notes

Verify the specific suffix (e.g., QDR) against the official datasheet to ensure correct package type and tape-and-reel specifications. Confirm that the automotive grade (Q1) meets your project's reliability requirements. Check for any recent lifecycle notices or obsolescence warnings directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when dual-channel isolation with integrated noise filtering is required for automotive or industrial use. Ensure the 3000 Vrms isolation rating matches system safety standards. Compare power consumption and propagation delay against other ISO732x variants if tighter timing or lower power is needed.

Part Context

This part belongs to the ISO732x-Q1 family of digital isolators. These devices are engineered for applications where short noise pulses may be present at input pins. The family offers various channel configurations and isolation ratings to suit different automotive and industrial design needs.

Replacement Considerations

Check the ISO732x-Q1 family datasheet for alternative pin-compatible parts with different channel counts or isolation voltages. Verify that any substitute maintains the same automotive qualification status and package dimensions.
