ISO7340FCDWR

Overview

The ISO7340FCDWR is a low-power, quad-channel digital isolator from Texas Instruments featuring a 4/0 channel configuration. It supports data rates up to 25 Mbps with a typical propagation delay of 31 ns. The device operates on a supply voltage range of 3 V to 5.5 V and draws a typical quiescent current of 6.4 mA per side. It provides galvanic isolation with an insulation voltage of 3000 Vrms. The component is housed in a 16-pin SOIC (DW) package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides four unidirectional signal channels for reliable data transmission across isolation barriers
• Integrates input noise filters to enhance signal integrity in electrically noisy environments
• Offers default output low logic state options for safe initialization upon power-up
• Delivers low power consumption suitable for battery-operated or energy-efficient systems

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interfacing and monitoring circuits
• Automotive electronic control units (ECUs) and sensor interfaces
• Power metering and smart grid communication modules

Procurement Notes

Verify the specific suffix 'FCDWR' corresponds to the 16-SOIC package and tape-and-reel packaging format. Confirm that the 4/0 channel configuration matches the system's directional requirements. Ensure the operating voltage range of 3 V to 5.5 V aligns with the target circuit design. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a quad-channel unidirectional isolator with low power consumption is needed. The 25 Mbps data rate suits moderate-speed industrial protocols. The 3000 Vrms insulation rating provides robust protection against high-voltage transients. Consider the 16-pin SOIC package for standard surface-mount assembly processes.

Part Context

This part belongs to the ISO7340FC family of low-power digital isolators. It complements other variants like the ISO7342FCDWR which offers bidirectional channels. The series is designed for applications demanding high reliability and electrical safety in compact form factors.

Replacement Considerations

Direct substitutes include ISO7340FCDW for cut-tape packaging. For bidirectional requirements, consider the ISO7342FCDWR. Verify pinout compatibility before replacing existing designs.
