ISO7830DW

Overview

The ISO7830DW is a triple-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC (DW) package. It supports data rates up to 100 Mb/s with unidirectional signal transmission. The device operates on a supply voltage range of 2.25 V to 5.5 V and features an insulation voltage rating of 5700 Vrms. Key electrical parameters include a propagation delay of 11 ns, rise/fall times of 3.9 ns, and a maximum power dissipation of 150 mW. It functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced isolation for three independent channels using capacitive coupling technology.
• Supports wide supply voltage ranges enabling level translation between 2.25 V and 5.5 V domains.
• Ensures high common-mode transient immunity suitable for noisy industrial environments.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-reliability signal separation
• Power metering circuits for accurate current and voltage sensing

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout and isolation ratings. Ensure the component meets RoHS compliance requirements for your region. Confirm that the SOIC-16 package dimensions align with your PCB footprint constraints before finalizing procurement decisions.

Selection Notes

Select this component when three isolated channels are required within a single package. Consider the 100 Mb/s data rate limit for signal integrity. Evaluate the 5700 Vrms insulation rating against system safety standards. Compare power consumption at 17.5 mA against other isolators if energy efficiency is critical.

Part Context

This part belongs to the ISO7830 series of digital isolators. It shares architectural similarities with the ISO7840 quad-channel variant but offers fewer channels. The DW package designation indicates a standard small-outline integrated circuit form factor compatible with surface-mount assembly processes.

Replacement Considerations

ISO7830DWR is the reel-packaged equivalent of the same functional device. Verify channel count and insulation ratings when substituting with other TI isolators like the ISO7741 or ISO7721 families.
