General Description
The MAX3160/MAX3161/MAX3162 are programmable +3V to +5.5V RS-232/RS-485/422 multiprotocol transceivers. The MAX3160/MAX3161 are pin programmable as a 2TX/2RX RS-232 interface or a single RS-485/422 transceiver. The MAX3162 is configured as a 2TX/2RX RS-232 interface and a single RS-485/422 transceiver simultaneously.

Benefits and Features
• Flexible Options for RS-232 and RS-422/485 Operation in One Package
    • Simultaneous 2TX/2RX RS-232 and Half-Duplex RS-485 Transceiver Operation (MAX3162)
    • Pin-Programmable as Either 2TX/2RX RS-232 or Half/Full RS-485 Transceiver (MAX3160, MAX3161)
• Integrated Protection Increases Robustness
    • Transmitters and Receivers Protected Against Wiring Faults
    • True Fail-Safe Receiver Prevents False Transition on Receiver Input Short or Open
    • Short-Circuit Protection Over the Entire CommonMode Voltage Range
    • Thermal Protection from Excessive Power Dissipation
    • Slew Rate Limiting Minimizes EM and Reduces Cable Reflections
• Integrated Charge-Pump Circuitry Saves Board Space
    • Eliminates the Need for a Bipolar ±12V Supply
    • Enables Single-Supply Operation From +3V to +5.5V Voltage Supply
• 1µA Shutdown Supply Current Saves Power
• Allows Up to 256 Transceivers on the Bus
