ISO7340FCQDWRQ1

Overview

The ISO7340FCQDWRQ1 is an automotive-grade, low-power, quad-channel reinforced digital isolator from Texas Instruments. It features four independent channels with unidirectional signal flow and capacitive coupling isolation technology. The device operates within a supply voltage range of 3 V to 5.5 V, consuming 9.3 mA of operating current. It supports data rates up to 25 Mb/s with a propagation delay of 31 ns. The component provides 3000 Vrms insulation voltage and is housed in a 16-pin SOIC package. It is qualified under AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability
• Reinforced digital isolation using capacitive coupling technology
• Low-power consumption suitable for energy-efficient designs
• Robust electromagnetic compatibility performance

Applications

• Automotive gate driver circuits
• Inverter control systems
• Motor drive applications
• On-board charger interfaces

Procurement Notes

Verify the specific suffix Q1 indicates automotive grade qualification. Confirm the DWR package variant matches the required SOIC-16 footprint. Ensure the manufacturer source is authorized to guarantee AEC-Q100 compliance. Check datasheet revisions for any updates to electrical characteristics or marking information before finalizing procurement specifications.

Selection Notes

Select this component when high channel count and automotive reliability are required. The quad-channel configuration reduces board space compared to single-channel alternatives. Consider the 25 Mb/s speed limit for application timing requirements. The unidirectional nature dictates signal flow direction constraints in the circuit design.

Part Context

This part belongs to the ISO734x-Q1 family of robust, low-power digital isolators. It shares architectural similarities with other members but offers four isolated channels. The series is designed for demanding automotive environments requiring enhanced safety and noise immunity.

Replacement Considerations

Consult official substitution lists for compatible variants within the ISO734x family. Verify pinout and electrical parameter compatibility before swapping components.
