ISO7320FCDR

Overview

The ISO7320FCDR is a dual-channel digital isolator from Texas Instruments, utilizing capacitive coupling technology. It features a unidirectional 2/0 channel configuration within an 8-SOIC package. The device supports data rates up to 25 Mbps with a typical propagation delay of 32 ns and offers 3000 VRMS isolation voltage. Operating on a supply voltage range of 3 V to 5.5 V, it draws approximately 4.9 mA per channel. The component is rated for operation between -40°C and +125°C.

Feature Summary

• Provides robust electromagnetic compatibility (EMC) performance with high common-mode transient immunity.
• Integrates input noise filters to suppress high-frequency interference signals.
• Delivers low-power operation suitable for energy-efficient system designs.
• Offers certified insulation ratings compliant with UL and VDE standards.

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power management interface circuits
• Smart grid monitoring devices

Procurement Notes

Verify the specific suffix 'F' indicates the required temperature or reliability grade compared to standard variants. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the unidirectional channel configuration aligns with your signal flow needs. Check for moisture sensitivity level handling during storage and reflow processes.

Selection Notes

Choose this component when bidirectional isolation is not required, as it provides only forward channels. Select based on the need for high common-mode transient immunity in noisy environments. Consider the power consumption profile against system battery life constraints. Verify that the 3000 VRMS isolation rating meets safety regulatory requirements for your application.

Part Context

This part belongs to the ISO732x family of digital isolators designed for robust EMC performance. It complements other variants like the ISO7320CDR by offering specific grading or testing parameters. The series focuses on providing reliable signal transmission across isolation barriers in industrial and medical applications.

Replacement Considerations

The ISO7320CDR serves as a direct functional substitute within the same family. Both share identical electrical specifications and pin configurations. Verify if the 'F' suffix denotes any specific manufacturing lot or enhanced testing criteria distinct from the standard 'C' variant.
