ISO7841DWW

Overview

The ISO7841DWW is a high-performance, reinforced quad-channel digital isolator manufactured by Texas Instruments. It features four forward channels and one reverse channel, supporting data rates up to 100 Mb/s with a propagation delay of 11 ns. The device operates on a supply voltage range of 2.25 V to 5.5 V and offers an insulation voltage of 5700 Vrms. It is housed in a 16-pin SOIC package and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced isolation for high-voltage noise immunity
• Integrates four forward and one reverse signal channel
• Supports high-speed data transmission at 100 Mbps
• Operates reliably across extended industrial temperature ranges

Applications

• Automotive electronic control units
• Medical equipment signal isolation
• Industrial communication interfaces
• Power metering systems

Procurement Notes

Verify the specific suffix 'DWW' indicates tube packaging rather than reel or cut tape formats when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the supplier provides valid traceability records for automotive or medical applications requiring strict quality assurance protocols.

Selection Notes

Select this component when reinforced isolation ratings are required for safety-critical applications. The integrated reverse channel facilitates bidirectional communication over a single isolated barrier. Consider the 16-pin SOIC footprint for PCB layout compatibility. Evaluate power consumption requirements against the specified operating supply current specifications.

Part Context

This part belongs to the ISO784x family of digital isolators from Texas Instruments. It shares architectural similarities with the ISO7840 but includes an additional reverse channel. The DWW suffix denotes a specific tube packaging variant suitable for automated assembly processes requiring high-volume production efficiency.

Replacement Considerations

The ISO7841DWWR serves as a direct pin-compatible alternative offering identical electrical characteristics but in reel packaging. Verify that any substitute maintains the same 5700 Vrms insulation rating and 100 Mbps data rate capabilities.
