DESCRIPTION

Description

OVERVIEW

Product Overview

The ISO1541DR is an isolated I²C bus device from Texas Instruments that supports bidirectional data and clock signal transfer across an isolation barrier. It targets I²C interfaces requiring galvanic isolation, helping block ground loops and protect low-voltage-side controllers. The SOIC-8 package supports conventional surface-mount production. Parameters such as isolation rating, data rate, supply range, and temperature grade should be obtained from the original datasheet; this entry does not provide or infer numerical values and makes no performance or certification claims.

APPLICATIONS

Applications

  • Interface an isolated I²C bus with a local controller.
  • Isolate communication signals in power or motor control systems.
  • Suitable for multi-board I²C communication requiring ground-loop breaking.
  • Used for bidirectional digital interfaces requiring electrical isolation in industrial equipment.
FEATURES AND BENEFITS

Features and Benefits

  • Supports bidirectional I²C data and clock signal transfer.
  • Provides electrical isolation that helps reduce ground-loop interference.
  • The isolation barrier helps protect low-voltage-side controller circuits.
  • SOIC-8 package supports conventional surface-mount assembly and replacement.
ADDITIONAL DETAILS

Additional Details

When ordering, confirm the package, packing, and temperature grade corresponding to the part number suffix, and check whether the isolation rating matches the target system requirements. Bus termination, pull-ups, and layout should be evaluated against the original datasheet.

Verify product details against the manufacturer datasheet before purchase.
