ISO7631FCDWR

Overview

The ISO7631FCDWR is a low-power digital isolator from Texas Instruments, featuring three channels in a 16-pin SOIC package. It supports bidirectional and unidirectional data transmission at speeds up to 150 Mbps. The device offers a peak isolation voltage of 4 kVpk and an RMS insulation voltage of 2500 Vrms using capacitive coupling technology. It operates on a single supply voltage ranging from 2.7 V to 5 V, with a maximum propagation delay of 7 ns. The component functions reliably within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides high-speed data transmission capabilities up to 150 Mbps for efficient signal integrity.
• Features low power consumption design suitable for energy-sensitive applications.
• Offers robust galvanic isolation with 4 kVpk peak isolation voltage rating.

Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing enhanced safety isolation barriers
• Power metering circuits for accurate data acquisition

Procurement Notes

Verify the specific suffix 'F' indicates automotive-grade qualification or specific reliability standards as defined by Texas Instruments. Confirm the 'DW' package designation matches the required 16-SOIC footprint dimensions. Ensure the datasheet version aligns with current manufacturing specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed data rates near 150 Mbps are required alongside low power constraints. The 16-SOIC package provides a compact solution for space-limited designs. Consider the 4 kVpk isolation rating for applications demanding higher transient immunity than standard 2.5 kVrms devices offer.

Part Context

This part belongs to the ISO7631 family of low-power digital isolators. It complements other variants like the ISO7631FMDW which shares similar electrical characteristics but differs in packaging configuration. The series is designed to replace optocouplers in modern interface applications.

Replacement Considerations

The ISO7631FMDW serves as a pin-compatible alternative within the same family, offering identical electrical performance in a different package style. Verify package dimensions and thermal requirements when substituting between DW and MDW variants.
