ISO7341FCDWR

Overview

The ISO7341FCDWR is a quad-channel reinforced digital isolator from Texas Instruments, housed in a 16-SOIC package. It features a 3/1 channel configuration with unidirectional data flow and supports data rates up to 25 Mb/s. The device provides 3000 Vrms isolation voltage and operates within a supply voltage range of 3 V to 5.5 V. Key electrical parameters include a propagation delay of 31 ns, a maximum rise time of 2.1 ns, and a maximum fall time of 1.7 ns. It functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via capacitive coupling technology for robust signal transmission.
• Features low fault protection mechanisms to maintain safe operation under adverse conditions.
• Designed for high electromagnetic compatibility (EMC) performance in noisy environments.

Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing reinforced insulation standards
• Power metering applications with high voltage separation needs

Procurement Notes

Verify the specific suffix 'FCDWR' corresponds to the 16-SOIC package and reel packaging format. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure input voltage levels match the specified 3 V to 5.5 V operating range to prevent functional errors.

Selection Notes

Select this component when reinforced isolation ratings and high EMC immunity are critical. The 3/1 channel layout suits designs requiring multiple isolated outputs with limited return channels. Consider the 31 ns propagation delay for timing-sensitive interfaces where moderate latency is acceptable.

Part Context

This part belongs to the ISO7341FC series of general-purpose digital isolators. It complements other variants in the family by offering specific isolation voltage and channel configurations tailored for safety-critical industrial and medical applications.

Replacement Considerations

Check datasheets for pin-compatible alternatives within the ISO7241 or ISO7341 families. Verify that substitute parts meet the same 3000 Vrms isolation requirement and SOIC-16 footprint constraints.
