ISO7830DWR

Overview

The ISO7830DWR is a Texas Instruments digital isolator featuring three forward channels and zero reverse channels in an SOIC-16 package. It utilizes capacitive coupling for isolation with a maximum insulation voltage of 5700 Vrms. The device supports data rates up to 100 Mb/s and operates on a supply voltage range of 2.25 V to 5.5 V. Key electrical parameters include a propagation delay of 11 ns, a typical operating supply current of 17.5 mA, and a power dissipation of 150 mW. It functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-voltage galvanic isolation between circuits using capacitive coupling technology.
• Supports unidirectional signal transmission across three independent channels.
• Enables level translation between different voltage domains within the specified supply range.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing enhanced safety isolation barriers
• Power electronics interfaces for gate drive applications

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-16 tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference pinouts with the latest datasheet revision to avoid compatibility issues during PCB layout.

Selection Notes

Select this component when three isolated bidirectional or unidirectional paths are required in a compact form factor. The 5700 Vrms rating suits applications demanding reinforced isolation standards. Consider the 100 Mbps speed limit for high-frequency digital communication needs. Evaluate power consumption against system thermal constraints given the 17.5 mA operating current.

Part Context

This part belongs to the ISO78xx series of high-performance digital isolators from Texas Instruments. It shares architectural similarities with the ISO7840 and ISO7820 but differs in channel count and directionality. The series is designed for industrial and automotive environments where reliability and noise immunity are critical.

Replacement Considerations

The ISO7830FDWWR is a documented variant within the same family offering similar functionality. Verify pin compatibility and electrical specifications before substitution. No other direct cross-model replacements are confirmed in public documentation.
