ISO7761FDWR

Overview

The ISO7761FDWR is a reinforced six-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It provides unidirectional signal isolation with a data rate of 100 Mb/s and a common-mode transient immunity of 85 kV/µs. The device operates on supply voltages between 2.25 V and 5.5 V, drawing typical quiescent currents of 11.5 mA and 30.5 mA for the two power domains. It features an insulation voltage rating of 5000 Vrms and a propagation delay of 11 ns. The component supports operation across a temperature range of -55°C to +125°C.

Feature Summary

• Reinforced insulation ratings for safety-critical applications
• Robust electromagnetic compatibility performance
• Six isolated channels for high-density signal routing

Applications

• Industrial automation systems
• Medical equipment isolation
• Power metering circuits

Procurement Notes

Verify the specific suffix 'FDWR' to confirm the SOIC-16 package and reel packaging configuration. Ensure the order matches the required reinforced insulation specifications rather than basic isolation variants. Confirm RoHS compliance status through official manufacturer documentation before procurement.

Selection Notes

Select this component when six independent isolated channels are required within a single package footprint. The 100 Mb/s data rate suits standard industrial communication protocols. Consider the 5000 Vrms insulation rating for applications requiring reinforced safety barriers between primary and secondary circuits.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators designed for robust EMC performance. Unlike the triple-channel ISO7831, this model offers six channels, providing higher integration density for complex multi-signal isolation requirements in space-constrained designs.

Replacement Considerations

Direct replacements include other ISO776x variants with compatible pinouts and electrical characteristics. Verify that substitute parts maintain the same reinforced insulation ratings and package dimensions to ensure mechanical and regulatory compliance.
