SP485R - 1/10th Unit Load RS-485 Transceiver

General Description

The SP485R is a pin-to-pin equivalent to our existing SP485 product and offers a 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.

Key Features

  • Allows Over 400 Transceivers On A Transmission Line (1/10th Unit Load).
  • High Impedance on Receiver Inputs (RIN = 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.
