ISOW1412BDFMR

Overview

The ISOW1412BDFMR is a reinforced isolated RS-485/RS-422 transceiver manufactured by Texas Instruments. It integrates a DC/DC converter and magnetic coupling technology to provide galvanic isolation. The device features four channels with a data rate of 500 kbps and a typical common-mode transient immunity of 100 kV/µs. It operates within a supply voltage range of 1.71 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. The component is housed in a 20-SOIC package.

Feature Summary

• Integrates a low-emissions DC/DC converter for isolated power generation
• Utilizes on-chip transformer technology for signal transmission
• Provides reinforced insulation capabilities for safety standards

Applications

• Industrial automation systems requiring isolated communication
• Medical equipment needing galvanic isolation
• Data acquisition systems with high noise environments

Procurement Notes

Verify the specific suffix 'BDFMR' against the official datasheet to confirm package dimensions and tape/reel specifications. Ensure compatibility with RoHS3 compliance requirements. Check for any recent Product Change Notifications regarding manufacturing site or material changes before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution for isolated RS-485/RS-422 communication is required. It is suitable for designs needing integrated power isolation to reduce external component count. Consider the 500 kbps data rate limit and the specific SOIC-20 footprint during PCB layout planning.

Part Context

This part belongs to the ISOW14x2 family of isolated transceivers. It shares architectural similarities with other members like the ISOW1432 but differs in data rate specifications. The family utilizes Texas Instruments' proprietary magnetic coupling technology for reliable signal transmission across isolation barriers.

Replacement Considerations

The ISOW1412DFMR is documented as a parameter-equivalent alternative.
