ISO7710DWR

Overview

The ISO7710DWR is a high-performance, single-channel reinforced digital isolator manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide robust signal isolation with a data rate of 100 Mb/s and a propagation delay of 11 ns. The device operates within a supply voltage range of 2.25 V to 5.5 V and draws a typical operating current of 5.9 mA. It features an insulation voltage rating of 5000 Vrms per UL 1577 standards. The component is housed in a 16-pin SOIC package and supports operation across an extended temperature range from -55°C to +125°C.

Feature Summary

• Provides reinforced single-channel digital isolation using capacitive coupling technology for high-speed signal transmission.
• Offers robust electromagnetic compatibility (EMC) performance suitable for noisy industrial environments.
• Delivers a long projected lifetime of over 30 years at 1500 VRMS working voltage.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment needing reinforced isolation for patient safety compliance.
• Power metering applications involving high-voltage measurement circuits.

Procurement Notes

Verify the specific suffix 'DW' corresponds to the 5000 VRMS isolation rating, as other variants may differ. Confirm the 'R' suffix indicates tape-and-reel packaging rather than cut tape or tube formats. Ensure the order matches the exact SOIC-16 package dimensions and pinout configuration required by the design. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components.

Selection Notes

Select this component when a single unidirectional channel with reinforced isolation is required. The 100 Mbps data rate suits moderate-speed communication interfaces. Consider the 5000 VRMS rating for applications demanding higher dielectric strength compared to standard isolation barriers. Evaluate the 16-pin SOIC footprint against available PCB space constraints.

Part Context

This device belongs to the ISO7710 series of digital isolators from Texas Instruments. It is designed to replace bulky magnetic couplers in modern electronic designs. The series offers various channel configurations and isolation ratings to meet diverse system requirements while maintaining small form factors.

Replacement Considerations

Check for ISO7710DR if reel packaging variations are needed. Verify ISO7710DW for identical electrical specifications but different packaging options. Ensure any substitute maintains the same 16-pin SOIC footprint and 5000 VRMS reinforcement rating.
