ISO7720DWR

Overview

The ISO7720DWR is a reinforced dual-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It supports unidirectional data transmission at rates up to 100 Mbps with a propagation delay of 17 ns. The device operates on supply voltages between 2.25 V and 5.5 V, drawing 11.6 mA. It provides 5000 Vrms isolation via capacitive coupling and withstands common-mode transients of 85 kV/µs. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Reinforced insulation barrier ensuring long-term reliability under high voltage stress
• High common-mode transient immunity for robust signal integrity in noisy environments
• Capacitive coupling technology enabling bidirectional isolation without magnetic interference

Applications

• Industrial communication interfaces requiring galvanic isolation
• Medical equipment signal conditioning circuits
• Power electronics control systems with high-voltage separation needs

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-16 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability.

Selection Notes

Select this component when reinforced isolation ratings are mandatory for safety standards. Consider the 100 Mbps speed limit and 17 ns delay for timing-critical applications. Evaluate power consumption against system constraints given the fixed operating current specifications.

Part Context
