ISO6763DWR

Overview

The ISO6763DWR is a general-purpose six-channel reinforced digital isolator manufactured by Texas Instruments. It features bidirectional data transmission with a maximum data rate of 50 Mb/s and a common-mode transient immunity of 50 kV/µs. The device operates within a supply voltage range of 1.71 V to 5.5 V and supports propagation delays up to 18 ns. It provides an insulation voltage rating of 5000 Vrms and functions across an operating temperature range from -40°C to +125°C. Packaged in a 16-pin SOIC (DW) format, it integrates three forward and three reverse channels without shutdown functionality.

Feature Summary

• Provides reinforced electrical isolation rated at 5000 Vrms for safety-critical applications
• Supports high-speed bidirectional communication with data rates up to 50 Mb/s
• Delivers robust noise immunity with a common-mode transient immunity of 50 kV/µs
• Compatible with standard digital interfaces including CAN, RS-232, RS-485, and SPI

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety barriers
• Power metering and energy management circuits
• Automotive electronic control units

Procurement Notes

Verify the specific suffix DWR corresponds to the SOIC-16 package and tape/reel orientation before ordering. Confirm that the required insulation ratings meet the safety standards of your target application, such as UL 1577 or VDE. Ensure the input voltage levels are compatible with the specified 1.71 V to 5.5 V operating range. Check for any recent product change notices regarding manufacturing sites or material composition updates.

Selection Notes

Select this component when a cost-effective solution for six isolated channels is required alongside high reliability. It is suitable for designs needing bidirectional data flow without individual channel shutdown controls. Consider alternatives if higher data rates exceeding 50 Mb/s or lower power consumption are primary constraints. Ensure the PCB layout accommodates the SOIC-16 footprint and creepage distances mandated by the 5000 Vrms isolation rating.

Part Context

This part belongs to the ISO676x family of high-performance digital isolators from Texas Instruments. These devices utilize capacitive coupling technology to provide signal isolation between different ground domains. The series is designed to replace bulky magnetic couplers while offering superior EMC performance and smaller form factors for modern embedded systems.

Replacement Considerations

ISO6763FDWR is listed as a parameter-equivalent substitute.
