ISO7641FCDWR

Overview

The ISO7641FCDWR is a low-power digital isolator from Texas Instruments featuring four channels in an SOIC-16 package. It provides unidirectional signal isolation with a data rate of 25 Mb/s and an insulation voltage of 2500 Vrms. The device operates on a supply voltage range of 3.3 V to 5 V, consuming only 1.3 mA of working power current. It exhibits a propagation delay of 17 ns and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Capacitive coupling technology for galvanic isolation
• Low power consumption design suitable for energy-efficient applications
• High common-mode transient immunity capabilities

Applications

• Industrial process control systems
• Power management circuits
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix 'W' confirms the reel packaging format when sourcing. Ensure the component matches the SOIC-16 footprint requirements for your PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component for designs requiring moderate speed isolation with minimal power draw. The 25 Mb/s rate suits standard communication protocols. Consider the 2500 Vrms rating against system safety standards. Evaluate thermal performance within the specified operating temperature limits.

Part Context

This part belongs to the ISO7641FC series of low-power digital isolators. It complements higher-speed variants like the ISO7640 by offering reduced power usage at lower data rates. The family shares similar pinouts but varies in electrical specifications.

Replacement Considerations

ISO7641FMDWR offers higher speed options within the same series.
