ISO7730DWR

Overview

The ISO7730DWR is a triple-channel digital isolator from Texas Instruments, housed in a 16-SOIC package. It supports a data rate of 100Mbps and offers an isolation rating of 5000Vrms with a common-mode transient immunity of 85kV/µs. The device operates on a supply voltage range of 2.25V to 5.5V and features a propagation delay of 16ns maximum. It provides three input channels and zero output channels, functioning as a unidirectional isolator suitable for harsh electromagnetic environments.

Feature Summary

• Robust EMC performance with high common-mode transient immunity
• Wide operating temperature range for industrial applications
• Single-supply level translation capability

Applications

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

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the 16-SOIC footprint matches your PCB design guidelines. Ensure the component meets the necessary UL safety certification standards for your target market regulations before finalizing procurement orders.

Selection Notes

Select this component when a triple-channel solution is required for galvanic isolation in noisy environments. The 100Mbps speed suits moderate-speed digital communication interfaces. Consider the 16-SOIC package size constraints and the 2.25V to 5.5V supply compatibility with your system logic levels during the design phase.

Part Context

This part belongs to the ISO773x family of reinforced digital isolators designed for robustness against electromagnetic interference. It utilizes capacitive coupling technology to transmit signals across the isolation barrier. The series is engineered to provide long-term reliability and compliance with international safety standards for isolated components.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISO773x series or other TI digital isolator families. Verify that any substitute maintains the same 5000Vrms isolation rating and 100Mbps data rate specifications to ensure circuit functionality remains unchanged.
