Features & Applications

The SP481R and SP485R are pin-to-pin equivalent with our existing SP485 product and contain enhancements such as higher ESD tolerance and high receiver input impedance.

The higher receiver input impedance allows for connecting over 400 transceivers on a single transmission line without degrading the RS-485 driver signal. Each device is packaged in an 8-pin plastic DIP or 8-pin narrow SOIC package.


  • Allows Over 400 Transceivers on Transmission Line (1/10th Unit Load)
  • High Impedance on Receiver Inputs (RI= 150kΩ typical)
  • Half-Duplex Configuration Consistent With Industry Standard Pinout
  • –7V to +12V Common Mode Input Voltage Range
  • Low Power Consumption (250mW)
  • Separate Driver and Receiver Enable
  • High-Fanout RS-485 Transceiver
