SP3071EEN-L/TR

The SP3070 - 3078E differential line transceivers are suitable for bidirectional communication on balanced multipoint bus transmission lines and comply with both RS485 and RS422 EIA Standards. Each device consists of a differential driver and differential receiver. All devices operate from a 3.3V power supply. High receiver input impedance allows a large number of transceivers to share a common data bus while maintaining signal margin and without excessive loading or use of expensive repeaters. The high impedance driver output is maintained over the entire common - mode voltage range from -7 to +12V. Receivers will failsafe to logic 1 output when inputs are open, shorted or terminated. Drivers include built - in short - circuit protection and a thermal - overload shutdown to protect against excessive power dissipation from bus contention or cable faults. All RS485 inputs are ESD protected up to ±15kV (Air - Gap and Human Body Model) and up to ±8kV Contact discharge (IEC 1000 - 4 - 2).
