ISO7241MDWRG4

Overview

The ISO7241MDWRG4 is a quad-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It operates on a supply voltage range of 3.3 V to 5 V with a maximum power dissipation of 18 mA. The device supports data rates up to 150 Mbps and provides an isolation voltage of 2500 Vrms via capacitive coupling. It features a 3:1 channel configuration (three forward, one reverse) and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Supports high-speed data transmission at rates up to 150 Mbps
• Offers bidirectional and unidirectional signal path flexibility
• Ensures safety compliance with reinforced insulation ratings

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation protection
• Power electronics monitoring and control circuits
• Automotive electronic control units (ECUs)

Procurement Notes

Verify the complete part number including the G4 suffix to ensure RoHS compliance and lead-free status. Confirm the SOIC-16 package type matches your PCB footprint requirements. Check for moisture sensitivity levels if storage conditions are not controlled. Ensure the operating voltage range aligns with your system's power supply specifications before ordering.

Selection Notes

Select this component when a quad-channel isolator with 150 Mbps speed is required. The 3:1 channel split suits applications with asymmetric data flow. Consider the 2500 Vrms isolation rating for safety-critical designs. Evaluate the -40°C to +125°C temperature range against environmental constraints. Compare pinout compatibility with existing designs to minimize layout changes.

Part Context

This device belongs to the ISO7241M family of digital isolators. It shares the SOIC-16 package and basic functionality with other members like the ISO7241DWRG4. The 'M' variant specifically denotes the 3:1 channel configuration. It complements Texas Instruments' broader portfolio of interface and isolation solutions for industrial and automotive markets.

Replacement Considerations

The ISO7241DW is a non-RoHS version of this component. Verify pin-to-pin compatibility when substituting. Ensure the replacement maintains the same 150 Mbps data rate and 2500 Vrms isolation rating. Check for any differences in propagation delay or power consumption characteristics.
