ISO7830DWW

Overview

The ISO7830DWW is a triple-channel digital isolator manufactured by Texas Instruments, housed in a 16-pin SOIC package. It provides high isolation ratings with an insulation voltage of 5700 Vrms and supports data rates up to 100 Mb/s. The device operates on supply voltages ranging from 2.25 V to 5.5 V, drawing a typical operating current of 13.2 mA. Key electrical parameters include a propagation delay of 11 ns, rise and fall times of 3.9 ns, and a pulse width distortion of 550 ps. It functions within a temperature range of -55°C to +125°C.

Feature Summary

• Triple-channel capacitive coupling isolation for signal transmission across isolation barriers
• High insulation rating supporting robust safety standards compliance
• Bidirectional and unidirectional channel configurations available
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-reliability signal isolation
• Power electronics monitoring and control circuits
• Communication interfaces in noisy electromagnetic environments

Procurement Notes

Verify the specific suffix (DWW vs DWWR) to confirm packaging type, as tube and reel variants exist. Confirm RoHS compliance status through official datasheets before integration. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Cross-reference pinouts with target PCB layout requirements to avoid compatibility issues during assembly.

Selection Notes

Choose this component when triple-channel isolation is required within a single package footprint. Compare against ISO7821 or ISO7841 if channel count or directionality differs. Evaluate power consumption at 13.2 mA against system budget constraints. Consider thermal dissipation capabilities given the 150 mW power rating in the SOIC-16 package.

Part Context

Part of the ISO78xx family of high-performance digital isolators from Texas Instruments. Designed to replace bulky magnetic isolators in modern electronic designs. Offers superior performance metrics compared to older optocoupler technologies. Integrates seamlessly into standard interface protocols while maintaining signal integrity.

Replacement Considerations

ISO7830DWWR serves as the reel-packaged equivalent. ISO7831DWW offers identical specifications with potential minor parameter variations. Verify pin-to-pin compatibility before substitution. Check updated datasheets for any revision differences affecting electrical characteristics.
