EVALUATION KIT AVAILABLE 15kV ESD-Protected, +3.0V to MAX3160E/MAX3161E/MAX3162E +5.5V, 10nA, RS-232/RS-485/ RS-422 Multiprotocol Transceivers General Description Benefits and Features The MAX3160E/MAX3161E/MAX3162E are programma- Flexible Options for RS-232 and RS-422/485 ble RS-232/RS-485/RS-422 multiprotocol transceivers. Operation In One Package The MAX3160E/MAX3161E are pin programmable as a Simultaneous 2Tx/2Rx RS-232 and Half-Duplex 2Tx/2Rx RS-232 interface or a single RS-485/RS-422 RS-485 Transceiver Operation (MAX3162E) transceiver. The MAX3162E is configured as a 2Tx/2Rx Pin-Programmable As Either 2Tx/2Rx RS-232 or RS-232 interface, and a single RS-485/RS-422 trans- Half/Full RS-485 Transceiver (MAX3160E, ceiver simultaneously. MAX3161E) The MAX3160E/MAX3161E/MAX3162E feature Integrated Protection Increases Robustness enhanced electrostatic discharge (ESD) protection. All High 15kV ESD HBM per JEDEC JS-001-2012 of the transmitter outputs and receiver inputs are pro- Transmitters and Receivers Protected Against tected to 15kV using the Human Body Model. Wiring Faults All devices incorporate a proprietary low-dropout trans- True Fail-Safe Receiver Prevents False Transition mitter output stage, and an on-board dual charge on Receiver Input Short or Open pump to allow RS-232- and RS-485-/RS-422-compliant Short-Circuit Protection Over the Entire Common- performance from a +3V to +5.5V supply. These Mode Voltage Range devices also feature pin-selectable transmitter slew Thermal Protection from Excessive Power rates for RS-232 and RS-485/RS-422 modes. Slew-rate Dissipation limiting minimizes EMI and reduces reflections caused Slew Rate Limiting Minimizes EM and Reduces by improperly terminated cables, allowing error-free Cable Reflections data transmission up to 250kbps. Disabling slew-rate Integrated Charge Pump Circuitry Saves Board limiting allows these devices to transmit at data rates Space up to 10Mbps in RS-485/RS-422 mode and up to Eliminates the Need for a Bipolar 12V Supply 1Mbps in RS-232 mode. Enables Single Supply Operation From +3V to The MAX3160E/MAX3162E offer a flow-through pin- +5.5V Voltage Supply out that facilitates board layout. The MAX3160E/ MAX3161E/MAX3162E are available in tiny SSOP pack- 1A Shutdown Supply Current Saves Power ages and operate up to -40C to +85C temperature Allows Up To 256 Transceivers on the Bus ranges.
