ISO7720FDWV

Overview

The ISO7720FDWV is a general-purpose digital isolator from Texas Instruments, featuring two forward channels and zero reverse channels in an 8-SOIC package. It utilizes capacitive coupling technology to provide 5000 Vrms isolation voltage with a data rate of 100 Mbps. The device operates on a supply voltage range of 2.25 V to 5.5 V, drawing 11.6 mA of operating current. Key electrical parameters include a maximum propagation delay of 16 ns, rise/fall times of 1.8 ns/1.9 ns, and a common-mode transient immunity of 85 kV/µs. It supports an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Provides robust electromagnetic compatibility through reinforced dual-channel isolation architecture
• Utilizes silicon dioxide-based capacitive coupling for high reliability and low power consumption
• Features unidirectional signal transmission with integrated logic type compatibility

Applications

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

Procurement Notes

Verify the specific suffix 'DWV' corresponds to the tube packaging format, as this variant is listed as obsolete. Confirm availability of recommended replacements like ISO7720FDWVR if new production is required. Ensure compliance with RoHS3 standards and check moisture sensitivity level (MSL 2) handling requirements during assembly.

Selection Notes

Select this component when reinforced isolation ratings are mandatory for safety-critical applications. The 8-SOIC package offers a compact footprint suitable for space-constrained designs. Consider the 100 Mbps data rate limit and 5000 Vrms isolation strength against system requirements. Evaluate the -55°C to +125°C temperature range for harsh environment suitability.

Part Context

Part of the ISO7720 family of digital isolators, designed for general-purpose use. It shares architectural similarities with other members but differs in channel configuration and insulation ratings. The device integrates capacitive sensing elements within a standard SOIC-8 outline, maintaining pinout compatibility with legacy isolators while offering improved performance metrics.

Replacement Considerations

ISO7720FDWVR is a manufacturer-recommended replacement offering identical electrical characteristics but in tape-and-reel packaging.
