ISO7760FDWR

Overview

The ISO7760FDWR is a high-speed, reinforced six-channel digital isolator from Texas Instruments. It features capacitive coupling technology with a data rate of 100 Mb/s and an insulation voltage of 5000 Vrms. The device operates on a supply voltage range of 2.25 V to 5.5 V, drawing 35 mA of working power current. It exhibits a propagation delay of 11 ns and rise/fall times of 3.9 ns. The component supports unidirectional signal transmission across all six channels without shutdown functionality. It is housed in a 16-pin SOIC package and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced isolation for robust EMC performance in high-speed digital communication
• Integrates six independent unidirectional channels for efficient multi-line signal isolation
• Utilizes capacitive coupling architecture to ensure reliable signal transmission across the isolation barrier

Applications

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

Procurement Notes

Verify the specific suffix 'F' indicates reinforced isolation ratings per UL standards compared to standard variants. Confirm the SOIC-16 package dimensions match your PCB footprint constraints. Ensure the operating temperature range meets your environmental specifications. Check humidity sensitivity levels for proper storage and reflow soldering profiles during assembly.

Selection Notes

Choose this component when six isolated channels are required for high-speed data transfer up to 100 Mb/s. Select this part if reinforced isolation certification is mandatory for regulatory compliance. Consider the 5000 Vrms rating for applications involving significant potential differences between circuits. Evaluate the 35 mA supply current against system power budget constraints.

Part Context

This device belongs to the ISO776x family of digital isolators designed for demanding industrial and medical environments. It offers a compact solution for replacing traditional optocouplers in space-constrained designs. The series provides enhanced reliability through silicon dioxide-based capacitive isolation technology.

Replacement Considerations

Direct replacements include other ISO776x variants such as ISO7760DWR or ISO7760QDWRQ1, depending on whether automotive qualification or standard industrial ratings are needed. Verify channel count and isolation voltage compatibility before substitution.
