ISO7830FDWW

Overview

The ISO7830FDWW is a triple-channel digital isolator from Texas Instruments, utilizing capacitive coupling technology to provide electrical isolation between circuits. It operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 100 Mb/s. The device features an insulation voltage rating of 5700 Vrms and maintains signal integrity with a propagation delay of 11 ns. Designed for robust performance, it functions across an extended temperature range from -55°C to +125°C. Packaged in a 16-pin SOIC (DW) format, the component draws a typical operating current of 17.5 mA.

Feature Summary

• Provides high-reliability galvanic isolation via capacitive coupling architecture
• Supports unidirectional signal transmission across three independent channels
• Enables wide supply voltage operation compatible with various logic levels

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing enhanced safety isolation barriers

Procurement Notes

Verify the specific suffix FDWW corresponds to the 16-SOIC tube packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the ordering part number matches the exact channel count and polarity requirements for your design implementation.

Selection Notes

Select this component when triple-channel isolation is required within a single package footprint. Consider the 100 Mb/s data rate limit and 11 ns propagation delay for timing-sensitive applications. Evaluate the 5700 Vrms insulation rating against system safety standards. Compare power consumption characteristics with alternative isolators if thermal management is critical.

Part Context

This device belongs to the ISO7830 series of digital isolators manufactured by Texas Instruments. The series focuses on providing high-performance isolation solutions using proprietary capacitive coupling technology. These components are designed to replace traditional optocouplers in modern electronic designs, offering improved speed and reliability.

Replacement Considerations

Check for ISO7830 variants with different packaging options or suffixes. Verify compatibility with existing board layouts when substituting similar triple-channel isolators.
