EVALUATION KIT AVAILABLE  
+3.0V to+5.5V, 1µA, RS-232/  
MAX3160/MAX3161/MAX3162  
General Description  
RS-485/422 Multiprotocol Transceivers  
Benefits and Features  
The MAX3160/MAX3161/MAX3162 are programmable  
+3V to +5.5V RS-232/RS-485/422 multiprotocol trans-  
ceivers. 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.  
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)  
All devices incorporate a proprietary low-dropout trans-  
mitter output stage and an on-board dual charge pump  
to allow RS-232 and RS-485/422 compliant perfor-  
mance from a +3V to +5.5V supply. These devices also  
feature pin-selectable transmitter slew rates for both  
RS-232 and RS-485/422 modes. Slew-rate limiting mini-  
mizes EMI and reduces reflections caused by improp-  
erly terminated cables, allowing error-free data  
transmission up to 250kbps. Disabling slew-rate limiting  
allows these devices to transmit at data rates up to  
10Mbps in RS-485/422 mode and up to 1Mbps in RS-  
232 mode.  
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 Common-  
Mode Voltage Range  
Thermal Protection from Excessive Power  
Dissipation  
Slew Rate Limiting Minimizes EM and Reduces  
Cable Reflections  
The MAX3160/MAX3162 offer a flow-through pinout that  
facilitates board layout. The MAX3160/MAX3161/  
MAX3162 are available in tiny SSOP packages and  
operate from -40°C to +85°C.  
Integrated Charge-Pump Circuitry Saves Board  
Space  
Eliminates the Need for a Bipolar 12V Supply
