ISO7331FCDWR

Overview

The ISO7331FCDWR is a general-purpose digital isolator from Texas Instruments featuring three channels in a 16-SOIC package. It provides 3000 Vrms isolation with a data rate of 25 Mbps and 25 kV/µs common-mode transient immunity. The device operates on a 3 V to 5.5 V supply, exhibits a maximum propagation delay of 31 ns, and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for high-speed digital signal transmission
• Features low-power consumption suitable for energy-efficient designs
• Offers robust common-mode transient immunity for noisy environments

Applications

• Industrial automation systems requiring signal isolation
• Medical equipment needing reliable galvanic separation
• Power metering applications for accurate data acquisition

Procurement Notes

Verify the specific suffix 'CDWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 3000 Vrms isolation rating meets the safety standards applicable to your target market. Ensure the 16-SOIC footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when three isolated channels are required within a single compact package. It is appropriate for designs prioritizing low power consumption alongside moderate data rates. Consider this part for applications where standard SOIC pin compatibility simplifies board redesign efforts compared to wider packages.

Part Context

This device belongs to the ISO73xx family of low-power digital isolators. It utilizes capacitive coupling technology to transmit signals across the isolation barrier. The family offers various channel configurations to support diverse interface requirements while maintaining consistent performance characteristics across the series.

Replacement Considerations

Check datasheets for ISO7231CDWR or ISO7331FCDW if alternative packaging or slight parameter variations are acceptable. Verify pinout compatibility and isolation voltage ratings before substituting to ensure circuit integrity.
