SP481R - High-Fanout RS-485 Transceiver

General Description

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.

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.
  • Includes Shutdown Mode (ICC < 10µA) (For SP481R Only).
  • Low Power Consumption (250mW).
  • Separate Driver and Receiver Enable Now Available in Lead Free Packaging.
