ISO1541DR +BOM

2.5-kVrms, isolated unidirectional clock, bidirectional I2C isolator

ISO1541DR General Description

The ISO1540 and ISO1541 isolators offer a unique solution for bidirectional communication in I2C interfaces. By utilizing Texas Instruments' Capacitive Isolation technology, these devices provide a reliable barrier against high voltages and noise currents. This technology not only ensures the safety of sensitive circuitry but also enhances overall performance and functionality compared to traditional optocouplers

Key Features

  • Isolated bidirectional, I2C compatible, communication
  • Supports up to 1-MHz operation
  • 3-V to 5.5-V supply range
  • Open-drain outputs With 3.5-mA Side 1 and 35-mA Side 2 sink current capability
  • –40°C to +125°C operating temperature
  • ±50-kV/µs transient immunity (Typical)
  • HBM ESD protection of 4 kV on all pins; 8 kV on bus pins
  • Safety-related certifications:
    • 4242-VPK isolation per DIN EN IEC 60747-17 (VDE 0884-17)
    • 2500-VRMS isolation for 1 minute per UL 1577
    • CSA approval per IEC 62368-1 end equipment standard
    • CQC basic insulation per GB4943.1-2011
