ISO7321CD

Overview

The ISO7321CD is a low-power, dual-channel digital isolator manufactured by Texas Instruments. It provides galvanic isolation with a rated insulation voltage of 3000 Vrms. The device supports data rates up to 25 Mbps and operates within a supply voltage range of 3 V to 5.5 V. It features a propagation delay of 33 ns and consumes 3.7 mA of operating current. The component is housed in an 8-SOIC package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Provides robust galvanic isolation between circuits
• Supports high-speed data transmission at 25 Mbps
• Operates with low power consumption for energy efficiency

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'CD' corresponds to the SOIC-8 package and standard operating temperature range. Confirm that the 3000 Vrms insulation rating meets system safety requirements. Ensure the 3 V to 5.5 V supply voltage compatibility aligns with the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation is required with a 3000 Vrms barrier. It is suitable for applications needing 25 Mbps throughput with minimal power draw. Consider the 8-SOIC footprint for surface-mount assembly constraints.

Part Context

This part belongs to the ISO7321 family of digital isolators designed for general-purpose isolation tasks. It utilizes capacitive coupling technology to transmit signals across isolation barriers while maintaining electrical separation.
