ISO7740DWR

Overview

The ISO7740DWR is a quad-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It supports unidirectional data transmission at speeds up to 100 Mb/s with a propagation delay of 10.7 ns. The device operates on a supply voltage between 2.25 V and 5.5 V, drawing 22.7 mA during operation. It provides an insulation rating of 5000 Vrms and withstands common-mode transients at 85 kV/µs. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Robust electromagnetic compatibility performance for reliable signal integrity
• Reinforced isolation barrier ensuring long-term safety compliance
• High-speed data transmission capability for efficient system communication

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety barriers
• Power metering applications with high-voltage interfaces

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 16-SOIC footprint matches your PCB design constraints. Ensure the component meets RoHS directives if applicable to your region. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when four independent unidirectional channels are necessary within a single package. Consider the 5000 Vrms isolation rating for applications demanding robust safety margins. Evaluate the 100 Mb/s data rate against your system's bandwidth requirements. Check the SOIC-16 package dimensions for space-constrained designs.

Part Context

This device belongs to the ISO7740 series of general-purpose digital isolators. It utilizes capacitive coupling technology to transmit signals across the isolation barrier. The series is designed to replace bulky optical couplers in modern electronic designs while offering superior performance and reliability.

Replacement Considerations

Check for ISO7740DR or ISO7740DW as alternative packaging options within the same family. Verify functional equivalence before substituting with other quad-channel isolators.
