ISO7242MDWRG4

Overview

The ISO7242MDWRG4 is a quad-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It supports bidirectional and unidirectional signal transmission with a data rate of 150 Mbps. The device provides 2500 Vrms insulation voltage using capacitive coupling technology. Operating supply voltage ranges from 3.3 V to 5 V, with a maximum power consumption of 15 mA per channel. Propagation delay is typically 15 ns. The component operates within an extended temperature range of -40°C to +125°C.

Feature Summary

• Provides four independent isolation channels for high-speed digital signal transmission
• Utilizes capacitive coupling technology to ensure robust electrical isolation between circuits
• Supports both bidirectional and unidirectional logic configurations for flexible system design

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation
• Power electronics control interfaces
• Communication gateways and protocol converters

Procurement Notes

Verify the RoHS compliance status and specific tape-and-reel packaging quantities before ordering. Confirm that the SOIC-16 footprint matches your PCB layout requirements. Ensure the operating voltage range aligns with your system's power supply rails. Check for any moisture sensitivity level restrictions during storage and handling.

Selection Notes

Select this component when four isolated channels are required at 150 Mbps speeds. Consider the 2500 Vrms isolation rating for safety-critical applications. Evaluate the 15 ns propagation delay against your timing constraints. Compare the 16-pin SOIC package size against available board space.

Part Context

This part belongs to the ISO7242M series of digital isolators. It is manufactured by Texas Instruments under the Interface ICs category. The device is designed to replace optocouplers in modern designs, offering higher speed and lower power consumption while maintaining reliable signal integrity across isolation barriers.

Replacement Considerations

Check for direct pin-compatible replacements within the same family. Verify if updated revisions offer improved performance or availability. Ensure substitute parts maintain the same isolation voltage and data rate specifications.
