ISO7230MDW

Overview

The ISO7230MDW is a triple-channel digital isolator from the ISO7230M series, manufactured by Texas Instruments. It features unidirectional signal transmission with a 3/0 channel configuration and supports data rates up to 150 Mbps. The device utilizes capacitive coupling technology to provide electrical isolation with an insulation voltage of 2500 Vrms. It operates within a supply voltage range of 3.15 V to 5.5 V and is housed in a 16-pin SOIC package. The component is designed for industrial applications requiring high electromagnetic immunity and low channel-to-channel output skew.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Supports high-speed digital signal transmission at rates up to 150 Mbps
• Features unidirectional data flow across three independent channels
• Offers high common-mode transient immunity for reliable operation in noisy environments

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits with high-voltage separation requirements
• Data acquisition systems with isolated sensor inputs

Procurement Notes

Verify current availability status as the ISO7230MDW may be discontinued or subject to production changes. Confirm that the replacement part number meets all original electrical specifications and pinout compatibility. Check for any recent Product Change Notices (PCN) affecting manufacturing location or materials. Ensure the selected substitute maintains the same package type and thermal characteristics for existing designs.

Selection Notes

Select this component when designing systems requiring triple-channel isolation with moderate data rates. Consider the 16-SOIC package constraints for PCB layout and thermal management. Evaluate the 2500 Vrms insulation rating against system safety standards. Verify that the 3.15 V to 5.5 V supply range aligns with the target logic levels and power budget of the application.
