ISO7810FDWWR

Overview

The ISO7810FDWWR is a high-voltage, reinforced single-channel digital isolator manufactured by Texas Instruments. It operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 100 Mbps. The device features an insulation voltage of 5700 VRMS and offers common-mode transient immunity of 100 kV/µs. It is housed in a 16-pin SOIC package with a width of 14.00 mm. The component functions unidirectionally with a propagation delay of 10.7 ns and operates across a temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced electrical isolation for safety-critical applications
• Utilizes capacitive coupling technology for signal transmission
• Ensures high common-mode transient immunity against noise
• Supports standard logic interface compatibility

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety barriers
• Power metering circuits for accurate signal separation
• Inverter drives and motor control interfaces

Procurement Notes

Verify the specific suffix 'DWR' confirms the reel packaging format upon ordering. Ensure the design accommodates the 16-SOIC footprint dimensions. Confirm that the 5700 VRMS rating meets the specific safety standards required by the target application environment. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a single unidirectional channel with reinforced isolation is required. It is suitable for designs needing high common-mode transient immunity at 100 Mbps. Consider the 16-pin SOIC package constraints for PCB layout. Evaluate power consumption needs as it draws current based on operating conditions.

Part Context

This part belongs to the ISO78xx family of digital isolators from Texas Instruments. These devices are designed to replace traditional optocouplers in modern applications. The family offers various channel counts while maintaining consistent performance metrics. The ISO7810 specifically addresses single-channel isolation needs.

Replacement Considerations

Direct substitutes include other ISO7810 variants with different packaging options such as ISO7810DW or ISO7810DR. Verify pinout compatibility before substitution. Ensure the replacement maintains the same insulation voltage and data rate specifications.
