ISO7640FMDWR

Overview

The ISO7640FMDWR is a low-power, quad-channel digital isolator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5 V and supports data rates up to 150 Mb/s. The device provides galvanic isolation with an insulation voltage of 2500 Vrms. Key electrical parameters include a propagation delay of 7 ns and power consumption of 8.2 mA or 35 mA depending on the channel configuration. It functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent unidirectional signal channels for digital isolation
• Utilizes capacitive coupling technology for galvanic isolation
• Designed for low power consumption applications
• Supports high-speed data transmission up to 150 Mbps

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power metering circuits with high-voltage isolation requirements
• Inverter drives and motor control systems

Procurement Notes

Verify the specific suffix 'W' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the selected variant matches the required channel count and polarity specifications for the target design.

Selection Notes

Select this component when four isolated channels are required in a single package. Consider the 2500 Vrms insulation rating against system voltage requirements. Evaluate the 150 Mbps data rate capability against signal timing needs. Compare power consumption figures against battery-operated constraints if applicable.

Part Context

This part belongs to the ISO7640FM family of low-power digital isolators. It shares the SOIC-16 package form factor with other variants in the series. The family focuses on providing robust isolation performance while minimizing energy usage in interface applications.

Replacement Considerations

Check for ISO7640FMDW as a tube-packaged alternative. Verify functional compatibility with ISO7641 series devices if channel configuration differs.
