Analog Devices (MAX3440EESA+) Transceiver RS422, RS485

Product OverviewThe MAX3440EESA+ is a ±15KV ESD protected, ±60V fault protected, fail-safe RS485transceiver in 8 pin NSOIC package. This fault protected RS485 transceiverfeature ±60V protection from signal faults on communication bus lines. Itcontains one differential line driver with three state output and ondifferential line receiver with three state input. The 1/4 unit load receiverinput impedance allows up to 128 transceivers on a single bus. True fail-safeinputs have a logic high receiver output when the receiver inputs are open,shorted or connected to an idle data line. Hot swap circuitry eliminates falsetransitions on the data bus during circuit initialization or connection to alive backplane. The on-chip ±15KV ESD protection eliminates costly externalprotection devices.Supply voltage range from 4.75V to 5.25VOperating temperature range from -40°C to 85°CData transfer rate is 250KbpsFeatures receiver/driver enable functionCommon mode input voltage range from -7V to +12VEnhanced slew rate limiting facilitates error free data transmissionApplicationsCommunications & 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 - UnlimitedIC Generic Number: MAX3440E
