Part Details

  • Isolation Breaks Ground Loops Due to High Common-Mode Voltages While Maintaining Data Rate
    • ±50V Isolation
    • 250kbps Guaranteed Data Rate
    • Active-Low FAULT Output Signals Excessive Isolated-Side Voltage
  • Integration of Isolation and RS-232 Saves Space
    • SSOP Package
  • Shutdown Allows Multiple Interfaces (IrDA, RS-232, RS-485) to be Connected to the Same UART
    • High-Impedance Transmitter and Receiver Outputs in Shutdown
    • 20µA Supply Current in Shutdown
  • Inductorless/Transformerless Design Simplifies EMI Compliance
  • Low-Cost Replacement for Opto-Isolated Transceivers
  • Meets EIA/TIA-232 Specifications Down to 3.0V
