Industrial Control, Utility Meters Building Automation, Instrumentation, Point of Sale
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).
