DESCRIPTION  
TheSP3070E-3078Edifferentiallinetransceiversaresuitableforbidirectionalcommunication  
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 receiver inputs and driver outputs are ESD protected up to ±15kV (Air-Gap and  
Human Body Model) and up to ±8kV Contact discharge (IEC 1000-4-2).
