ISO7240CFDWG4

Overview

The ISO7240CFDWG4 is a quad digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It provides four unidirectional channels with a data rate of 25 Mbps and an insulation voltage of 2500 Vrms. The device features selectable failsafe outputs and operates on a supply voltage range of 3.15 V to 5.5 V. It utilizes capacitive coupling technology for signal isolation.

Feature Summary

• Provides four isolated digital channels for high-speed signal transmission
• Features selectable failsafe output logic to ensure defined states during fault conditions
• Utilizes capacitive coupling technology for robust signal isolation

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced or basic isolation barriers
• General-purpose digital communication interfaces

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as indicated in official documentation. Check current lifecycle status, as this part may be obsolete or subject to discontinuation notices from the manufacturer.

Selection Notes

Select this component when four isolated channels are required with selectable failsafe functionality. Ensure the operating voltage matches the 3.15 V to 5.5 V range. Verify that the 2500 Vrms insulation rating meets system safety requirements.

Part Context

This part belongs to the ISO7240C series of digital isolators. It shares the SOIC-16 footprint with other variants like the ISO7240CDWG4 but includes specific selectable failsafe logic characteristics distinguishing it from standard versions.
