SP485 - Low Power Half-Duplex RS-485 Transceivers

Download the SP485 datasheet PDF. This datasheet also covers the SP483 variant, as both devices belong to the same low power half-duplex rs-485 transceivers family and are provided as variant models within a single manufacturer datasheet.

Description

The SP483 and SP485 are a family of half-duplex transceivers that meet the specifications of RS-485 and RS-422.

Their BiCMOS design allows low power operation without sacrificing performance.

The SP485 meets the requirements of RS-485 and RS-422 up to 5Mbps.

Features

  • +5V Only.
  • Low Power BiCMOS.
  • Driver / Receiver Enable.
  • Slew Rate Limited Driver for Low EMI (SP483).
  • Low Power Shutdown mode (SP483).
  • RS-485 and RS-422 Drivers/Receivers.
