ISO7230CDW

Digital Isolators Overview

The ISO7230CDW is a triple-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It supports data rates up to 25 Mbps with unidirectional signal transmission across three forward channels and zero reverse channels. The device operates within a supply voltage range of 3.15 V to 5.5 V and features an insulation voltage of 2500 Vrms using capacitive coupling technology. Key electrical parameters include a typical propagation delay of 56 ns and a maximum rise time of 2 ns. It functions reliably in industrial temperatures from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation for three independent signal paths using high-speed capacitive coupling technology.
• Supports unidirectional data transmission with low channel-to-channel output skew and minimal pulse-width distortion.
• Operates within a wide temperature range suitable for demanding industrial environments.

Digital Isolators Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing high-voltage safety barriers
• Power metering circuits for accurate data acquisition

Digital Isolators Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and isolation requirements before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Digital Isolators Selection Notes

Select this component when triple-channel isolation is required at moderate data speeds. Consider the SOIC-16 footprint for PCB layout constraints. Evaluate CMTI ratings if high dv/dt noise immunity is critical for the application environment.

Digital Isolators Part Context

This device belongs to the ISO7230C series of digital isolators. It complements other TI interface solutions by offering integrated isolation without external magnetic components. The series provides options for varying data rates and channel configurations to suit diverse interface needs.

Digital Isolators Replacement Considerations

Check for ISO7230CDWR as a reel-based alternative with identical specifications. Verify pinout compatibility when substituting with similar triple-channel isolators from other manufacturers.
