The SP3070E-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 +2V. Receivers will failsafe to logic 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 ±5kV (Air-Gap and
Human Body Model) and up to ±8kV Contact discharge (IEC 6000-4-2). The SP3070E-
SP3078E devices may not achieve optimal transmit performance if the connected receiver
includes a biasing network to 5.0V without a termination resistor. Please see ExarApplication
Note ANI#2 for further details.
