Maxim Integrated (MAX489CSD+) RS485/RS422, Transmitter/Receiver

Product OverviewThe MAX489CSD+ is a slew-rate-limited Low-power Transceiver for RS-485 andRS-422 communications. Each part contains one driver and one receiver. TheMAX489 feature reduced slew-rate drivers that minimize EMI and reducereflections caused by improperly terminated cables, thus allowing error-freedata transmission up to 250kbps. These transceivers draw between 120 and 500µAof supply current when unloaded or fully loaded with disabled drivers. Driversare short-circuit current limited and are protected against excessive powerdissipation by thermal shutdown circuitry that places the driver outputs into ahigh-impedance state. The receiver input has a fail-safe feature that guaranteesa logic-high output if the input is open circuit. The MAX489 is designed forfull-duplex applications.Receiver/driver enable120µA Quiescent current32 Number of receivers on bus14 Pin countApplicationsCommunications & 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: SOICNo. of Pins: 14PinsOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
