Product Summary
The SP3074EEN differential line transceiver is suitable for bidirectional communication on balanced multipoint bus transmission lines and comply with both RS485 and RS422 EIA Standards. The SP3074EEN consists of a differential driver and differential receiver. The SP3074EEN operates 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 of the SP3074EEN is maintained over the entire common-mode voltage range from -7 to +12V. Receiver 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).
