SP3070E - 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.

Key Features

  • ±15kV ESD protection for RS-485 pins.
  • 3.3V low-power operation.
  • Advanced receiver-failsafe protection for open, shorted or terminated lines.
  • Up to 256 transceivers may share Bus.
  • Very low load for 8x greater fanout.
  • Hot Swap glitch protection RE and DE.
  • Thermal shutdown protects against driver contention.
  • Available in three industry standard footprints  SP3070E, SP3073E and SP3076E in Full-Duplex (14-pin)  SP3071E, SP3074E and SP3077E in Full-Duplex (.

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.
