ISO7230ADWG4

Overview

The ISO7230ADWG4 is a Texas Instruments digital isolator featuring three unidirectional channels with capacitive coupling technology. It operates within a supply voltage range of 3.15 V to 5.5 V and supports data rates up to 1 Mb/s. The device provides an isolation voltage of 3000 Vrms and functions across an extended temperature range from -40°C to +125°C. Key electrical parameters include a propagation delay of 95 ns, a typical rise time of 2 ns, and a power dissipation of 220 mW. It is housed in a 16-pin SOIC package.

Feature Summary

• Provides galvanic isolation via capacitive coupling for signal integrity
• Supports high-speed digital communication at 1 Mbps
• Operates reliably in extreme industrial temperatures

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering interface circuits

Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm RoHS compliance and moisture sensitivity levels before integration. Check for alternative sourcing options as availability may be restricted. Ensure proper handling procedures are followed during storage and assembly to prevent damage to the sensitive internal isolation barrier.

Selection Notes

Select this component when three isolated bidirectional or unidirectional paths are required at moderate speeds. Compare against ISO7231 variants if bidirectional capability is needed. Consider thermal management requirements given the 220 mW dissipation. Validate that the 3000 Vrms insulation rating meets system safety standards.

Part Context

Part of the ISO7230A family of general-purpose digital isolators. Designed for robust performance in noisy environments. Replaces older optocoupler solutions with smaller footprint and lower power consumption. Compatible with standard SOIC-16 mounting styles for easy PCB layout integration.

Replacement Considerations

ISO7230CDWR offers higher speed but different insulation ratings. ISO7231ADWRG4 provides bidirectional channel support. Verify pin compatibility and electrical specifications before substitution.
