ISO7810DWW

Overview

The ISO7810DWW is a single-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It features capacitive coupling technology with a 5700 Vrms isolation rating and supports data rates up to 100 Mbps. The device operates on a supply voltage between 2.25 V and 5.5 V, drawing 1.8 mA of operating current. Key electrical parameters include a propagation delay of 10.7 ns, rise/fall times of 2.4 ns, and pulse width distortion of 4.6 ns. It functions within a temperature range of -55°C to +125°C and offers 100 kV/µs common-mode transient immunity.

Feature Summary

• Provides reinforced insulation for high-voltage separation using capacitive coupling technology
• Ensures signal integrity with low propagation delay and minimal pulse width distortion
• Supports unidirectional data transmission for reliable single-channel isolation

Applications

• Industrial automation systems requiring galvanic isolation
• Embedded systems with mixed-signal ground domains
• Medical equipment needing reinforced safety isolation

Procurement Notes

Verify the specific suffix 'DWW' to confirm the tube packaging format, as the 'DWWR' variant uses tape-and-reel packaging. Ensure the component meets RoHS compliance requirements for your region. Confirm that the 16-SOIC footprint matches your PCB design constraints. Check for moisture sensitivity level (MSL) handling requirements during assembly. Validate that the 5.5 V maximum supply voltage aligns with your system power rails.

Selection Notes

Select this component when a single-channel, unidirectional isolator is required for high-speed digital signals. It is suitable for applications demanding 5700 Vrms working isolation voltage. Consider the 100 Mbps data rate limit for bandwidth requirements. The wide operating temperature range makes it appropriate for harsh industrial environments. Ensure the 1.8 mA quiescent current fits your power budget constraints.

Part Context

This part belongs to the ISO7810 family of high-performance digital isolators. It shares architectural similarities with other members like the ISO7810DWWR but differs in packaging. The series is designed for robust noise immunity and low power consumption. It complements Texas Instruments' broader portfolio of interface ICs for isolated communication.

Replacement Considerations

The ISO7810DWWR is a direct functional substitute with identical electrical specifications, differing only in packaging (tape-and-reel vs. tube). Verify that the change in packaging does not impact your automated assembly process or storage conditions.
