ISO6760LNDWR

Overview

The ISO6760LNDWR is a six-channel unidirectional digital isolator manufactured by Texas Instruments. It features integrated interlock functionality and utilizes capacitive coupling technology. The device supports data rates up to 50 Mbps and provides an isolation rating of 5000 Vrms. Common mode transient immunity is specified at 50 kV/µs. It operates within a supply voltage range of 2.25 V to 5.5 V and functions across a temperature range of -55°C to +125°C. The component is housed in a 16-pin SOIC package.

Feature Summary

• Integrated interlock mechanism prevents false triggering during power-up or fault conditions
• Capacitive coupling technology enables high-speed signal transmission with low power consumption
• Six independent channels provide efficient multi-channel isolation in a compact footprint

Applications

• Industrial automation systems requiring robust galvanic isolation
• Medical equipment needing enhanced safety isolation standards
• Power electronics interfaces for motor drives and inverters

Procurement Notes

Verify the complete part number including the NDWR suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the required isolation voltage ratings align with your system's safety certifications. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure ESD handling procedures are followed due to the sensitivity of CMOS interface circuits.

Selection Notes

Select this component when six isolated channels are required in a single package to reduce board space. The integrated interlock feature is critical for applications where signal integrity during startup is paramount. Consider the 50 kV/µs CMTI rating for environments with high dv/dt noise. Verify that the SOIC-16 package dimensions fit your PCB layout constraints and thermal requirements.

Part Context

This device belongs to the ISO676x family of digital isolators from Texas Instruments. These components are designed to replace traditional optocouplers in modern designs, offering superior performance in speed, power efficiency, and size. The family includes variants with different channel counts and isolation levels, catering to diverse industrial and commercial interface needs.

Replacement Considerations

The ISO6762DWR is a related six-channel variant but lacks the integrated interlock feature found in the ISO6760LNDWR. Designers must evaluate whether the interlock functionality is necessary for their specific application before substituting. Other family members may offer different channel configurations or isolation ratings.
