Overview
The ISOW7741BDFMR is a quad-channel digital isolator from Texas Instruments featuring an integrated DC-DC converter. It provides galvanic isolation with a maximum data rate of 100 Mb/s and a common-mode transient immunity of 85 kV/µs. The device operates within a supply voltage range of 2.97 V to 5.5 V and supports bidirectional signal transmission across four channels. It is housed in a 20-pin SOIC package designed for surface-mount installation.
Feature Summary
- Integrates a low-emissions, low-ripple DC-DC converter for isolated power generation
- Provides robust galvanic isolation with high common-mode transient immunity
- Supports bidirectional communication across four independent channels
Applications
- Industrial automation systems requiring reinforced isolation
- Medical equipment needing safe isolation barriers
- Automotive electronics demanding high reliability
Procurement Notes
Verify the specific suffix 'BDFMR' against official datasheets to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the intended PCB footprint and reflow soldering profile. Confirm that the integrated DC-DC converter meets the noise requirements of the application environment.
Selection Notes
Select this component when a single-chip solution for both signal isolation and isolated power is required. It eliminates the need for external isolated power supplies, reducing board space. Consider the 85 kV/µs CMTI rating for environments with high dv/dt noise. Verify thermal performance under maximum load conditions.
Part Context
This part belongs to the ISOW774x family of quad-channel digital isolators with integrated converters. It differs from non-integrated variants by providing on-chip power conversion. The 'B' suffix typically denotes a specific revision or qualification level within the series.
Replacement Considerations
Direct substitutes include other ISOW774x variants such as ISOW7740FDFMR or ISOW7742FDFMR, provided channel configurations match. Non-integrated alternatives like ISO7741 require separate isolated power sources.
