RS-485/422 multiprotocol Transceivers General Description Benefits and Features The MAX3160/MAX3161/MAX3162 are programmable Flexible Options for RS-232 and RS-422/485. +3V to + RS-232/ RS-485/422 multiprotocol trans- Operation in One Package ceivers. The MAX3160/MAX3161 are pin programmable Simultaneous 2TX/2RX RS-232 and Half-Duplex as a 2TX/2RX RS-232 interface or a single RS-485/422 RS-485 transceiver Operation (MAX3162). transceiver . The MAX3162 is configured as a 2TX/2RX. Pin-Programmable as Either 2TX/2RX RS-232 or RS-232 interface and a single RS-485/422 transceiver simultaneously. 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 Integrated Protection Increases Robustness to allow RS-232 and RS-485/422 compliant perfor- Transmitters and Receivers Protected Against mance from a +3V to + supply.

Slew-rate limiting mini- mizes EMI and reduces reflections caused by improp- on Receiver Input Short or Open erly terminated cables, allowing error-free data Short-Circuit Protection Over the Entire Common- transmission up to 250kbps. Disabling slew-rate limiting Mode Voltage Range allows these devices to transmit at data rates up to Thermal Protection from Excessive Power 10 Mbps in RS-485/422 mode and up to 1 Mbps in RS- Dissipation 232 mode. Slew Rate Limiting Minimizes EM and Reduces The MAX3160/MAX3162 offer a flow-through pinout that Cable Reflections facilitates board layout. The MAX3160/MAX3161/. MAX3162 are available in tiny SSOP packages and Integrated Charge-Pump Circuitry Saves Board operate from -40 C to +85 C.
