Maxim Integrated (MAX14858GWE+) Transceiver RS422, RS485

Product OverviewThe MAX14858GWE+ is a 5KVRMS isolated 25Mbps full duplex RS485/RS422 transceiverin 16 pin WSOIC package with ±35KV ESD protection. The MAX14856GWE+ isolatedRS-485/RS-422 transceiver provides 5000VRMS (60s) of galvanic isolation betweenthe cable-side (RS485/RS422 driver/receiver side) and the UART side of thedevice. The isolation improves communication by breaking ground loops andreduces noise when there are large differences in ground potential betweenports. The device includes one drive channel and one receive channel. Thereceiver is 1/4-unit load allowing up to 128 transceivers on a common bus.Integrated true fail-safe circuitry ensures a logic-high on the receiver outputwhen inputs are shorted or open. Undervoltage lockout disables the driver whencable-side or UART-side power supplies are below functional levels. It is usedin industrial automation equipment, programmable logic controllers and powermeters.Supply voltage range from 1.71V to 5.5V, LDO supply voltage range from 3.18V to14VIntegrated LDO for cable side power, compliant with RS-485 EIA/TIA-485 standardIntegrated protection ensures for robust communication, thermal shutdown±35KV ESD (HBM) on driver outputs/receiver inputs, 848VRMS max working-isolationvoltage (VIOWM)Maximum 1200V repetitive peak-isolation voltage (VIORM)Lifetime at rated working voltage is > 30 years withstands ±10KV surge per IEC61000-4-5Maximum driver and receiver propagation delay is 65nsCommon mode transient immunity is 35KV/µsOperating temperature range from -40°C to 105°CApplicationsHVACProduct InformationDevice Type: TransceiverIC Interface Type: RS422, RS485No. of Drivers: 1DriversNo. of Receivers: 1ReceiversSupply Voltage Min: 1.71VSupply Voltage Max: 5.5VDriver Case Style: WSOICNo. of Pins: 16PinsOperating Temperature Min: -40°COperating Temperature Max: 105°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
