Analog Devices (MAX3085ECPA+) Transceiver RS422, RS485

Product OverviewThe MAX3085ECPA+ is a ±15KV ESD protected, fail-safe, slew rate limitedRS485/RS422 transceiver in 8 pin DIP package. It contains one driver and onereceiver. The device features fail-safe circuitry which has a logic highreceiver output when the receiver inputs are open or shorted. This means thatthe receiver output will be logic high if all transmitters on a terminated busare disabled (high impedance). MAX3085ECPA+ offers higher driver output slewrate limits allowing transmit speeds up to 500Kbps. The transmitter output andreceiver input is protected by ±15KV using human body model with enhanced ESDprotection. This transceiver typically draws 375µA of supply current whenunloaded or when fully loaded with the drivers disabled. It has a 1/8 unit loadreceiver input impedance that allows up to 256 transceivers on the bus.Supply voltage range from 4.75V to 5.25VOperating temperature range from 0°C to 70°CIntended for half duplex communicationTrue fail-safe receiver while maintaining EIA/TIA485 compatibility1nA low current shutdown modeFeatures receiver/driver enable functionApplicationsCommunications & Networking, IndustrialProduct InformationDevice Type: TransceiverIC Interface Type: RS422, RS485No. of Drivers: 1DriversNo. of Receivers: 1ReceiversSupply Voltage Min: 4.75VSupply Voltage Max: 5.25VDriver Case Style: DIPNo. of Pins: 8PinsOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
