Maxim Integrated (MAX3089ECSD+) Transceiver RS422, RS485

Product Overview The MAX3089ECSD+ is a ±15KVESD protected, fail-safe, high speed RS485/RS422 transceiver in 14 pin NSOIC package. It contains one driver and one receiver. The device features fail-safe circuitry which has a logic high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be logic high if all transmitters on a terminated bus are disabled (high impedance). MAX3089ECSD+ slew rate is selectable between 115Kbps, 500Kbps and 10Mbps by driving a selector pin with a single three-state driver. The transmitter output and receiver input is protected by ±15KV using human body model with enhanced ESD protection. This transceiver typically draws 375µA of supply current when unloaded or when fully loaded with the drivers disabled. It has a 1/8 unit load receiver input impedance that allows up to 256 transceivers on the bus. Supply voltage range from 4.75V to 5.25V Operating temperature range from 0°C to 70°C Selectable between half duplex and full duplex operation True fail-safe receiver while maintaining EIA/TIA485 compatibility 1nA low current shutdown mode Features receiver/driver enable function Phase controls to correct for twisted pair reversal Applications Communications & Networking, Industrial Product Information Device Type: Transceiver IC Interface Type: RS422, RS485 No. of Drivers: 1Drivers No. of Receivers: 1Receivers Supply Voltage Min: 4.75V Supply Voltage Max: 5.25V Driver Case Style: NSOIC No. of Pins: 14Pins Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
