SP485R High-Fanout RS-485 Transceiver

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. The device is packaged in a 8-pin plastic DIP or 8-pin narrow SOIC

技术特性
  • 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
