ISO7631FMDWR

Digital Isolators Overview

The ISO7631FMDWR is a low-power digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It features three channels with two unidirectional and one bidirectional path. The device supports data rates up to 150 Mbps and offers a propagation delay of 7 ns. It operates on a supply voltage between 2.7 V and 5 V. The isolation rating is 2500 Vrms, utilizing capacitive coupling technology. The component functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates three isolated channels for signal transmission.
• Supports high-speed data transfer at 150 Mbps.
• Provides galvanic isolation via capacitive coupling.

Digital Isolators Applications

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

Digital Isolators Procurement Notes

Verify the specific suffix 'W' confirms the reel packaging format against official documentation. Ensure the order matches the exact channel configuration and insulation requirements. Confirm RoHS compliance status through the manufacturer's latest release notes. Validate that the SOIC-16 footprint aligns with the target PCB design constraints.

Digital Isolators Selection Notes

Choose this model when three isolated channels are required for mixed polarity signals. The bidirectional channel simplifies circuit design for half-duplex communication. Select based on the need for low power consumption in battery-operated devices. Consider the 7 ns delay for timing-sensitive applications requiring precise synchronization.

Digital Isolators Part Context

This part belongs to the ISO7631FM series of low-power digital isolators. It complements other variants like the ISO7631FCDWR by offering different packaging options. The series is designed for robust performance in noisy environments. It serves as a key component for breaking ground loops in complex electronic systems.

Digital Isolators Replacement Considerations

The ISO7631FMDW is the tube-packaged equivalent of this reel version. Both share identical electrical specifications and pinouts. Verify package dimensions remain consistent during substitution. Ensure the replacement maintains the same thermal and isolation ratings.
