ISO7760DWR

Overview

The ISO7760DWR is a high-performance, six-channel digital isolator from Texas Instruments. It features capacitive coupling technology with a 5000 Vrms isolation rating per UL 1577. The device supports data rates up to 100 Mb/s and operates within a supply voltage range of 2.25 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 11 ns, typical rise/fall times of 1.1 ns/1.4 ns, and a common-mode transient immunity of 85 kV/µs. It functions in an ambient temperature range of -55°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Six-channel unidirectional signal isolation using robust capacitive coupling technology
• High common-mode transient immunity for reliable operation in noisy environments
• Wide operating temperature range suitable for industrial applications
• Low pulse width distortion for accurate high-speed data transmission

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power metering circuits for energy monitoring
• Inverter drives and motor control units

Procurement Notes

Verify the specific suffix DWR indicates the SOIC-16 tape-and-reel packaging configuration. Confirm that the 5000 Vrms rating applies specifically to this package variant as defined by UL 1577 standards. Ensure compatibility with the required 2.25 V to 5.5 V supply rails before integration into the design.

Selection Notes

Select this component when six isolated channels are required in a single package. It is suitable for designs prioritizing high EMC robustness and wide temperature stability. Compare against lower channel count variants if fewer signals need isolation. Ensure the 100 Mb/s data rate meets the system's bandwidth requirements.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators. It shares architectural similarities with other members like the ISO7740 but offers increased channel density. The series is designed to replace traditional optocouplers in modern electronic systems, providing better performance and smaller form factors.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISO776x family. Verify that substitute parts maintain the same 5000 Vrms isolation rating and SOIC-16 footprint. Ensure thermal and electrical characteristics match the original design specifications.
