ISO7310FCDR

Overview

The ISO7310FCDR is a low-power, single-channel digital isolator from Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mbps. The device provides galvanic isolation with an insulation voltage of 3000 Vrms. Key electrical parameters include a typical propagation delay of 32 ns and a maximum operating power supply current of 3.8 mA. It functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in an 8-pin SOIC package.

Feature Summary

• Provides robust electromagnetic compatibility (EMC) performance for noisy environments
• Offers high common-mode transient immunity to prevent signal errors
• Delivers low-power operation suitable for energy-efficient designs

Applications

• Industrial process control systems
• Medical equipment signal isolation
• Power metering applications

Procurement Notes

Verify the specific suffix 'CDR' corresponds to the SOIC-8 tape-and-reel packaging configuration required for automated assembly. Confirm that the 3000 Vrms insulation rating meets the safety standards applicable to your target market, such as UL or VDE certifications. Ensure the unidirectional channel architecture aligns with the signal flow requirements of the circuit design.

Selection Notes

Select this component when a single isolated channel is sufficient for the application. It is appropriate for designs requiring moderate data speeds up to 25 Mbps. Consider this part if low quiescent current is a priority compared to higher-speed alternatives. Verify that the SOIC-8 footprint fits the available board space constraints.

Part Context

This device belongs to the ISO731x family of digital isolators. These components utilize capacitive coupling technology to transmit signals across an isolation barrier. The family includes variants with different channel counts and configurations, all sharing similar core isolation characteristics and pinout structures for ease of integration.

Replacement Considerations

Check for direct replacements within the ISO731x series that may offer different channel configurations or updated packaging options while maintaining compatible electrical specifications.
