Part Description: MAX3160 DS


Part Details:

19-1722; Rev 1; 3/06 +3.0V to+5.5V, 1µA, RS-232/RS-485/422 Multiprotocol Transceivers MAX3160/MAX3161/MAX3162 General Description Features The MAX3160/MAX3161/MAX3162 are programmable Single-Supply Operation from +3V to +5.5V RS-232/RS-485/422 multiprotocol transceivers. TheMAX3160/MAX3161 are pin programmable as a 2TX/2RX Pin-Programmable as 2TX/2RX RS-232 or Single RS-232 interface or a single RS-485/422 transceiver. The RS-485/422 (MAX3160/MAX3161) MAX3162 is configured as a 2TX/2RX RS-232 interface 2TX/2RX RS-232 and Single RS-485/422 and a single RS-485/422 transceiver simultaneously. (MAX3162) All devices incorporate a proprietary low-dropout trans- Pin-Programmable RS-232/RS-485 Transmitter mitter output stage and an on-board dual charge pumpto allow RS-232 and RS-485/422 compliant perfor- Slew Rates Reduce EMI mance from a +3V to +5.5V supply. The receivers 10Mbps RS-485 and 1Mbps RS-232 Data Rates feature true fail-safe circuitry that guarantees a logic- Pin-Programmable Half-Duplex or Full-Duplex high receiver output when the receiver inputs are openor shorted. These devices also feature pin-selectable RS-485/422 Operation (MAX3160/MAX3161) transmitter slew rates for both RS-232 and RS-485/422 RS-485/422 True Fail-Safe Receivers modes. Slew-rate limiting minimizes EMI and reduces Transmitters and Receivers Protected Against reflections caused by improperly terminated cables,allowing error-free data transmission up to 250kbps. Wiring Faults Disabling slew-rate limiting allows these devices to 1µA Shutdown Supply Current transmit at data rates up to 10Mbps in RS-485/422 1/8-Unit Load Allows up to 256 Transceivers on mode and up to 1Mbps in RS-232 mode. TheMAX3160/MAX3161/MAX3162 feature a 1µA shutdown the Bus mode, and short-circuit limiting and thermal shutdowncircuitry to protect against excessive power dissipation. The MAX3160/MAX3162 offer a flow-through pinout thatfacilitates board layout. The MAX3160/MAX3161/MAX3162 are available in tiny SSOP packages andoperate over the commercial and extended tempera-ture ranges.
