2.5-kVrms voltage rating for safe operation

ISO1541D General Description

The ISO1540 and ISO1541 devices from Texas Instruments offer a cutting-edge solution for low-power, bidirectional isolation in I2C interfaces. By utilizing Capacitive Isolation technology with a silicon dioxide barrier, these devices effectively block high voltages, isolate grounds, and prevent noise interference, ensuring the protection of sensitive circuitry. This technology also delivers superior function, performance, size, and power consumption benefits compared to traditional optocouplers, making it an ideal choice for compact applications

Key Features

  • ISO 1541D features include standardization of document file formats, compliance with international standards, compatibility with various operating systems, efficient data management, and secure data transfer
  • It also offers support for multiple languages, annotations, and metadata, ensuring proper documentation and information preservation
  • Application

  • The ISO1541D is commonly used in communication systems, industrial automation, automotive applications, and medical devices for implementing galvanic isolation between the communication interfaces to protect sensitive electronics and ensure reliable data transmission
