DESCRIPTION

Description

OVERVIEW

Product Overview

The ISOW1412DFMR is an isolated RS-485/RS-422 transceiver from Texas Instruments that integrates an isolated power supply and signal isolation channels, providing electrical isolation between the bus side and the logic side in a single device. It is intended for industrial fieldbus communication, motor drives, and programmable logic controllers where isolation is required, helping reduce system size and simplify isolated power design. It is housed in a wide-body SOIC-20 package.

APPLICATIONS

Applications

  • Isolated RS-485 interfaces for industrial fieldbus communication nodes.
  • Isolated communication links in motor drive and motion control systems.
  • Isolated bus connections for programmable logic controllers and distributed I/O.
  • Communication interfaces in industrial instruments requiring isolated power and data channels.
FEATURES AND BENEFITS

Features and Benefits

  • Integrated isolated power reduces external isolated power components.
  • Supports RS-485/RS-422 bus transceiver functions.
  • Provides electrical isolation between the bus side and the logic side.
  • Wide-body package facilitates isolation creepage distance layout.
ADDITIONAL DETAILS

Additional Details

When purchasing, verify the exact part number suffix and package type, and confirm whether isolation rating, data rate, and supply range meet the design requirements; refer to the original datasheet for pin definitions and recommended operating conditions.

Verify product details against the manufacturer datasheet before purchase.
