ISO6721RFBDR

Overview

The ISO6721RFBDR is a general-purpose dual-channel digital isolator from Texas Instruments, featuring a reverse pinout configuration. It operates with a supply voltage range of 1.71 V to 5.5 V and supports data rates up to 50 Mb/s. The device provides bidirectional signal transmission with a typical propagation delay of 15 ns. It utilizes capacitive coupling for isolation, offering an insulation voltage of 3000 Vrms. Packaged in an SOIC-8 (D) format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Reverse pinout design facilitates PCB layout flexibility
• Bidirectional channel architecture for versatile signal routing
• Capacitive coupling technology ensures robust isolation

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering interface circuits

Procurement Notes

Verify the specific suffix 'R' indicates the reverse pinout variant distinct from standard configurations. Confirm package type matches SOIC-8 requirements. Ensure operating conditions align with the specified voltage and temperature ranges. Check for RoHS compliance status as documented. Validate that the bidirectional feature meets system signal flow needs.

Selection Notes

Select this component when bidirectional communication is required alongside reverse pinout compatibility. Compare against unidirectional variants if signal directionality differs. Consider the 50 Mb/s speed limit for high-frequency applications. Evaluate power consumption at 6 mA against system constraints. Ensure thermal management supports the extended temperature range.

Part Context

Part of the ISO6721 family, designed for general-purpose isolation tasks. The RFBDR variant specifically addresses layout challenges through its reversed pin arrangement. It complements other devices like the ISO6721FBDR by offering alternative connectivity options. The series emphasizes reliability in noisy environments using capacitive isolation principles.

Replacement Considerations

ISO6721RBDR serves as a direct functional substitute with identical electrical characteristics but may differ in packaging or ordering suffix details. Verify pinout compatibility before substitution.
