Application Scenarios & Design Considerations

Full Duplex RS-485 Transceivers

Alternative Part Number

  • MAX491ECPD --: Pin-compatible RS-485/RS-422 transceiver with the same ESD protection and low-power characteristics, widely available and a direct functional drop-in for the SP1491EEN.
  • SN75176BP --: Industry-standard RS-485 differential bus transceiver in a DIP package, functionally equivalent for most SP1491EEN applications and very cost-effective.
  • ADM485ANZ --: Low-power RS-485 transceiver with similar pinout and electrical specs, suitable as a reliable second-source alternative when the original Sipex part is unavailable.
