ISO7762DWR

Overview

The ISO7762DWR is a high-performance, six-channel digital isolator from Texas Instruments. It features a data rate of 100 Mb/s and provides an isolation voltage rating of 5000 Vrms per UL 1577 standards. The device utilizes capacitive coupling for signal transmission and operates within a supply voltage range up to 5.5 V. Designed for robust EMC performance, it offers reinforced isolation barriers with a projected lifetime exceeding 30 years. The component is housed in a SOIC-16 package (DW) and supports bidirectional communication across all six channels.

Feature Summary

• Six-channel digital isolation with 100 Mbps data rate
• Reinforced isolation barrier rated at 5000 VRMS
• Robust electromagnetic compatibility (EMC) design
• Capacitive coupling technology for signal transmission

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with high-voltage separation
• Inverters and motor control circuits

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-16 wide-body package and tape-and-reel quantity when ordering. Confirm that the required isolation rating meets the 5000 VRMS specification for your application's safety standards. Ensure compatibility with the 5.5 V maximum supply voltage and check for any specific RoHS compliance documentation required by your region. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when six isolated channels are required within a single package to save board space. It is suitable for designs demanding high-speed data transfer up to 100 Mbps alongside strong noise immunity. Consider the SOIC-16 footprint constraints and thermal requirements during PCB layout. Compare against lower channel count variants if fewer isolation points are sufficient for the system architecture.

Part Context

This device belongs to the ISO776x family of high-performance digital isolators. The family includes variants with different channel counts and package options, such as the DBQ package offering 3000 VRMS ratings. The ISO7762 specifically provides six channels, distinguishing it from four-channel or eight-channel counterparts in the same series.

Replacement Considerations

Check for direct pin-to-pin replacements within the ISO776x family, such as other ISO776x variants with compatible packaging. Verify that alternative components meet the same 5000 VRMS reinforced isolation rating and 100 Mbps speed requirement. Ensure any substitute maintains the SOIC-16 form factor for existing board layouts.
