ISO7710FDWR

Overview

The ISO7710FDWR is a single-channel reinforced digital isolator from Texas Instruments featuring capacitive coupling technology. It supports data rates up to 100 Mb/s with a propagation delay of 11 ns and pulse width distortion of 600 ps. The device operates on supply voltages between 2.25 V and 5.5 V, drawing 5.9 mA of operating current. It provides an isolation rating of 5000 Vrms and withstands common-mode transients at 85 kV/µs. Operating temperatures range from -55°C to +125°C in an SOIC-16 package.

Feature Summary

• Reinforced single-channel isolation barrier designed for robust electromagnetic compatibility
• Capacitive coupling architecture enabling high-speed signal transmission up to 100 Mbps
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with high voltage separation needs

Procurement Notes

Verify the specific suffix FDWR indicates the SOIC-16 package and tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance requirements as specified in the manufacturer datasheet. Ensure the ordering part number matches the exact pinout and insulation ratings required for your circuit design before finalizing procurement.

Selection Notes

Select this component when a single-channel isolated interface is required with high CMTI performance. The 100 Mbps data rate suits moderate-speed communication links. Consider the SOIC-16 footprint for PCB layout constraints. Verify that the 5000 Vrms isolation rating aligns with safety standards applicable to the target application environment.

Part Context

This device belongs to the ISO7710 family of digital isolators. It shares architectural similarities with other members like the ISO7710FDR but differs in package type and shipping format. The family utilizes Texas Instruments' capacitive isolation technology to provide reliable signal transmission across isolation barriers without optical components.

Replacement Considerations

ISO7710FDR offers identical electrical specifications but uses an 8-SOIC package instead of SOIC-16. ISO7710QDWRQ1 is the automotive-grade equivalent qualified under AEC-Q100 standards. Verify pin compatibility and thermal characteristics when substituting these variants.
