Analog Devices (MAX3465CSD+) Transceiver RS422, RS485

Product OverviewThe MAX3465CSD+ is a +5V, fail-safe, profibus RS485/RS422 transceiver in 14 pinNSOIC package. This high speed and full duplex differential bus transceiver isdesigned to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11 and X.27 standards. Itcomplies with profibus specification providing +2.1V minimum output level with54ohm load and 40Mbps data rate. The MAX3465 contains one three statedifferential line driver and one differential input line receiver. The deviceoperates from +5V supply and features true fail-safe circuitry which provideslogic high receiver output when receiver inputs are open or shorted. Thisenables all receiver outputs on a terminated bus to output logic highs when alltransmitters are disabled. It has 1/4 standard unit load receiver inputimpedance that allows 128 transceivers on the bus. The driver and receiver hasactive-high and active-low enables respectively and can be connected togetherexternally to serve as a direction control. It is used in level translators.Supply voltage range from 4.75V to 5.25VOperating temperature range from 0°C to 70°C15ns transmitter propagation delay and 20ns receiver propagation delay2ns transmitter and receiver skewDesigned for multipoint transmissions on long or noisy bus linesHigh differential driver output level (2.1V on 54ohm)1µA shutdown supply current and low supply current of 2.5mAPhase controls to correct for twisted pair reversalCurrent limiting and thermal shutdown for driver overload protectionReceiver/driver enable, low power shutdown mode, hot swap function andindependent shutdown pinApplicationsCommunications & 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: NSOICNo. of Pins: 14PinsOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - UnlimitedIC Generic Number: MAX3465
