ISO7762DW

Overview

The ISO7762DW is a high-speed, robust EMC six-channel digital isolator from Texas Instruments. It features reinforced isolation ratings of 5000-VRMS per UL 1577 standards. The device supports data rates up to 100 Mb/s with typical propagation delays of 11 ns and rise/fall times around 1.1 ns to 1.4 ns. It operates on supply voltages between 2.25 V and 5.5 V. Key performance metrics include a common-mode transient immunity (CMTI) of 85 kV/µs and pulse width distortion of 4.9 ns maximum. It is housed in a 16-SOIC package.

Feature Summary

• Provides reinforced insulation for safety-critical applications
• Ensures signal integrity through robust electromagnetic compatibility
• Delivers high-speed data transmission across isolation barriers

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing certified safety isolation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and isolation ratings. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Check for RoHS compliance status as indicated in current datasheets. Confirm package availability matches project requirements before finalizing orders.

Selection Notes

Select this component when reinforced isolation is mandatory for safety certification. Consider the six-channel configuration for complex multi-signal isolation needs. Evaluate the 100 Mb/s speed against system timing requirements. Verify that the 16-SOIC footprint fits the PCB layout constraints effectively.

Part Context

This part belongs to the ISO776x family of digital isolators designed for high-performance applications. It complements other variants like the ISO7763DWR which offers different channel configurations. The series emphasizes reliability in noisy environments while maintaining strict isolation boundaries for personnel protection.

Replacement Considerations

Direct substitutes within the same family include the ISO7762DBQ for smaller packages. Cross-referencing with ISO7763DWR may be necessary if channel counts differ. Always validate electrical parameters against the original design specifications before substitution.
