ISO7741BDWR

Overview

The ISO7741BDWR is a quad-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It features capacitive coupling for signal isolation with a maximum insulation voltage of 5000 Vrms. The device supports data rates up to 100 Mb/s and operates on supply voltages between 2.25 V and 5.5 V. It provides three forward channels and one reverse channel, with a propagation delay of 10.7 ns. Operating temperatures range from -55°C to +125°C, and the unit draws 8.6 mA or 18 mA depending on configuration.

Feature Summary

• Provides robust electromagnetic compatibility performance through reinforced isolation architecture
• Utilizes capacitive coupling technology to ensure high-speed digital signal transmission across isolation barriers
• Configures four independent channels with a 3-forward and 1-reverse topology for flexible system integration

Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing reinforced electrical safety standards
• Power electronics interfaces demanding high common-mode transient immunity

Procurement Notes

Verify the specific suffix 'BDWR' to confirm the SOIC-16 surface-mount package and tape-and-reel shipping format. Ensure the component meets the required insulation voltage specifications for your application's safety standards. Check current lifecycle status as older variants may be subject to obsolescence notices from the manufacturer.

Selection Notes

Select this model when a quad-channel isolator with reinforced isolation ratings is necessary. Compare power consumption requirements against the specified operating currents. Consider the thermal dissipation capabilities within the SOIC-16 package for your specific board layout constraints.

Part Context
