The SP3070E-3078E differential line transceivers are suitable forbidirectional communication on balanced multipoint bus transmissionlines and comply with both RS485 and RS422 EIA Standards. Each deviceconsists of a differential driver and differential receiver. All devicesoperate from a 3.3V power supply.High receiver input impedance allows a large number of transceivers toshare a common data bus while maintaining signal margin and withoutexcessive loading or use of expensive repeaters. The high impedancedriver output is maintained over the entire common-mode voltage rangefrom -7 to +12V. Receivers will failsafe to logic 1 output when inputsare open, shorted or terminated. Drivers include built-in short-circuitprotection and a thermal-overload shutdown to protect against excessivepower dissipation from bus contention or cable faults. All RS485receiver inputs and driver outputs are ESD protected up to ±15kV(Air-Gap and Human Body Model) and up to ±8kV Contact discharge (IEC1000-4-2).For technical support or help choosing a product please email Exar’s Serial Technical Support group at:?serialtechsupport@exar.com.
