ISO7330CDW

Overview

The ISO7330CDW is a triple-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It operates on a supply voltage range of 3 V to 5.5 V with a typical operating current of 4.3 mA. The device supports data rates up to 25 Mb/s and features a propagation delay of 32 ns. It provides 3000 Vrms isolation voltage using capacitive coupling technology and offers a common-mode transient immunity of 25 kV/µs. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for three independent signal channels
• Utilizes capacitive coupling technology for robust signal transmission
• Supports high-speed data transfer at rates up to 25 Mb/s
• Ensures reliable operation across an extended industrial temperature range

Applications

• Industrial process control systems
• Profibus communication networks
• General-purpose isolated digital interfaces

Procurement Notes

Verify the specific suffix 'CDW' to confirm the SOIC-16 package and tape-and-reel or tube availability as required by your assembly line. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders to ensure regulatory adherence.

Selection Notes

Select this component when three isolated bidirectional channels are required within a single compact footprint. It is suitable for designs needing moderate speed isolation with low power consumption. Ensure the system voltage aligns with the 3 V to 5.5 V input range and that the thermal environment stays within the specified operational limits.

Part Context

This part belongs to the ISO7330C series of general-purpose digital isolators. It is designed to replace bulky magnetic couplers in modern electronic circuits. The device integrates high-speed CMOS technology with silicon dioxide-based isolation barriers to provide enhanced safety and reliability in noisy environments.

Replacement Considerations

Check for ISO7330FCDW if higher insulation ratings are needed. Verify pin compatibility with existing PCB layouts when substituting similar channel counts.
