SP3078EEN-L

The SP3078EEN-L is a Differential Line Transceiver for bidirectional communication on balanced multipoint bus transmission lines and comply with both RS485 and RS422 EIA standards. The device consists of a differential driver and differential receiver. It 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 is maintained over the entire common-mode voltage range from -7 to 12V. The Receivers will failsafe to logic 1 output when inputs are open, shorted or terminated. Driver includes 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.
