ISO7710DR

Overview

The ISO7710DR is a single-channel digital isolator from Texas Instruments, housed in an SOIC-8 package. It operates on a supply voltage range of 2.25 V to 5.5 V with a typical operating current of 5.9 mA. The device supports data rates up to 100 Mb/s and features unidirectional signal transmission. It provides a reinforced insulation rating of 3000 Vrms per UL 1577 standards. Key timing parameters include a propagation delay of 11 ns, rise/fall times of 3.9 ns, and pulse width distortion of 0.6 ns. It functions within a temperature range of -55°C to +125°C.

Feature Summary

• Robust EMC performance for reliable operation in noisy environments
• Capacitive coupling isolation technology ensuring high reliability
• Single-channel unidirectional data transmission capability

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with high voltage separation needs

Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-8 tape-and-reel packaging configuration. Confirm that the 3000 Vrms rating aligns with your system's safety requirements, as other variants may offer higher ratings. Ensure compliance with RoHS directives and check humidity sensitivity handling procedures during assembly.

Selection Notes

Select this component when a single-channel, unidirectional isolator is required. It is suitable for designs needing 3000 Vrms reinforced isolation at 100 Mbps. Consider the SOIC-8 footprint for PCB layout constraints. Evaluate power consumption against system budgets given the 5.9 mA typical current draw.

Part Context

This part belongs to the ISO7710 family of high-speed digital isolators. The family includes variants with different channel counts and isolation ratings. The ISO7710 specifically focuses on single-channel applications, offering a balance between speed, power efficiency, and robust isolation performance for general-purpose use.

Replacement Considerations

Check for ISO7710D (cut tape) or ISO7710DW (DW package with 5000VRMS rating) if packaging or isolation level differs. Verify pinout compatibility before substitution.
