ISO7330FCDWR

Overview

The ISO7330FCDWR is a triple-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It operates on a supply voltage between 3 V and 5.5 V with a typical quiescent current of 7 mA per channel. The device supports data rates up to 25 Mbps and provides an insulation voltage of 3000 Vrms. It features unidirectional signal transmission with a propagation delay of 32 ns and a common-mode transient immunity of 25 kV/µs. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for three independent signal channels using capacitive coupling technology.
• Ensures robust noise immunity against high-frequency electromagnetic interference through specified common-mode transient immunity ratings.
• Supports low-power operation suitable for battery-driven or energy-constrained automotive applications.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems utilizing isolated sensor data acquisition
• Power electronics monitoring circuits needing high-voltage separation

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when ordering. Confirm that the 'Q1' designation is required if automotive qualification under AEC-Q100 standards is necessary for your specific application environment. Ensure the SOIC-16 footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required within a single compact package. It is appropriate for designs needing 3000 Vrms isolation strength with moderate data throughput. Consider alternative models if higher channel counts or different isolation voltages are needed.

Part Context

This part belongs to the ISO7330 family of low-power, triple-channel digital isolators. It shares architectural similarities with other members like the ISO7330FCQDWRQ1 but differs in packaging and specific qualification levels. The series is designed to replace optocouplers in modern automotive and industrial systems.

Replacement Considerations

The ISO7330FCQDWRQ1 serves as a qualified automotive alternative with similar electrical characteristics. Verify pin compatibility and isolation voltage ratings when substituting with other ISO7330 variants to ensure system integrity.
