ISO6741FDWR

Overview

The ISO6741FDWR is a quad-channel, 3/1 digital isolator manufactured by Texas Instruments. It features capacitive coupling for galvanic isolation with a maximum data rate of 50 Mb/s and supports 1.8V logic. The device operates within a supply voltage range of 1.71 V to 5.5 V. Key electrical parameters include a propagation delay of 11 ns and an insulation voltage rating of 5000 Vrms. It is housed in a 16-pin SOIC (DW) package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Provides reinforced galvanic isolation via capacitive coupling technology
• Supports high-speed signal transmission up to 50 Mb/s
• Compatible with low-voltage logic systems including 1.8V operation

Applications

• Automotive display applications
• Industrial signal isolation
• High-performance signal isolation circuits

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm that the component meets automotive display requirements if applicable. Ensure the design accommodates the specified 1.8V logic support and 5000 Vrms insulation rating. Check for humidity sensitivity handling during assembly. Validate compatibility with the 16-pin SOIC footprint.

Selection Notes

Select this component for designs requiring robust isolation between microcontrollers and peripheral devices. It is suitable for environments demanding high noise immunity and reliable signal integrity. Consider the 3/1 channel configuration for asymmetric data flow needs. Evaluate power consumption against system constraints given the operating current specifications.

Part Context

This part belongs to the ISO6741 family of general-purpose digital isolators from Texas Instruments. It shares architectural similarities with other members like the ISO6741DWR but differs in packaging and tape-and-reel configuration. The series is designed to replace traditional optocouplers in modern electronic systems.

Replacement Considerations

The ISO6741DWR serves as a tube-packaged alternative within the same functional family. Verify pinout compatibility before substitution. Ensure the replacement meets the required insulation voltage and data rate specifications.
