SP3078E

SP3070E - SP3078E Family Data Sheet ±15kV ESD-Protected, 3.3V, 1/8 Load, Failsafe RS-485/RS-422 Transceivers General Description The SP3070E - SP3078E differential line transceivers are suitable for bidirectional communication on balanced multi-point bus transmission lines and comply with both RS-485 and RS-422 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 RS-485 receiver inputs and driver outputs are ESD protected up to ±15kV (Air-Gap and Human Body Model) and up to ±8kV Contact Discharge (IEC 61000-42). 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.
