Analog Devices (MAX3462ESA+) Transceiver RS422, RS485

Product OverviewThe MAX3462ESA+ is a +5V, fail-safe, 20Mbps, profibus RS485/RS422 transceiver in8 pin NSOIC package. It is designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11and X.27 standards. The transceiver complies with the profibus specificationproviding +2.1V output level with a 54ohm load, 20Mbps data rate and output skewless than 2ns. It contains one three-state differential line driver and onedifferential input line receiver. The device operate from a +5V supply and has atrue fail-safe circuitry which gives a logic-high receiver output when thereceiver inputs are open or shorted. This enables all receiver outputs on aterminated bus to output logic highs when all transmitters are disabled. It hasa 1/4 standard unit load receiver input impedance that allows 128 transceiverson the bus. This device is widely used in high speed RS485 communications, highspeed RS422 communications, level translators and profibus applications.Supply voltage range is 4.75V to 5.25VOperating temperature range from -40°C to 85°CTransmitter and receiver propagation delay is 20nsLow supply current requirements (2.5mA typ)Shutdown supply current is 1µADesigned for multipoint transmissions on long or noisy bus linesFull duplex communicationCurrent limiting and thermal shutdown for driver overload protectionApplicationsCommunications & 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: 8PinsOperating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
