ISO7230ADW

Overview

The ISO7230ADW is a triple-channel digital isolator from Texas Instruments, utilizing capacitive coupling technology for signal transmission. It operates within a supply voltage range of 3.15 V to 5.5 V and supports data rates up to 1 Mbps. The device features an isolation voltage rating of 4000 Vpk and a common-mode transient immunity of 25 kV/µs. Packaged in a 16-pin SOIC (DW) format, it provides unidirectional signal paths with three forward channels and zero reverse channels. The component functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Capacitive coupling architecture ensures robust signal integrity across isolation barriers
• High common-mode transient immunity protects against noise interference
• Wide operating temperature range supports demanding industrial environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high-voltage interfaces

Procurement Notes

Verify the specific suffix 'DW' confirms the 16-pin SOIC package and lead-free status. Confirm the 'A' grade designation matches required performance specifications. Check current lifecycle status as distribution availability may vary by region. Ensure RoHS compliance documentation is available for regulatory requirements.

Selection Notes

Select this component when three isolated channels are required at 1 Mbps speeds. Consider the 4000 Vpk isolation rating for safety-critical designs. Evaluate the 16-pin SOIC footprint against board space constraints. Compare power consumption and propagation delay against alternative isolators if low latency is critical.

Part Context

This part belongs to the ISO7230A family of general-purpose digital isolators. It shares the same core isolation technology and pinout compatibility with other variants in the series, differing primarily in speed grades and insulation ratings. The family addresses diverse interface needs across industrial and consumer electronics sectors.

Replacement Considerations

Direct substitutes include ISO7230ADWR for tape-and-reel packaging or ISO7230CDW for higher speed options. Verify pin compatibility and electrical parameters before substitution.
