MAX3162EAI集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

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
