• Isolation Breaks Ground Loops Due to High CommonMode Voltages While Maintaining Data Rate
• ±50V Isolation
• 250kbps Guaranteed Data Rate
• 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 |
