Application Scenarios & Design Considerations

Enhanced Quad RS-485/RS-422 Line Drivers

Alternative Part Number

  • MAX487ECPA+ --: Pin-compatible RS-485/RS-422 transceiver with the same ESD protection and low-power shutdown features, widely available and a direct functional drop-in for the SP487EET.
  • SN75176BP --: Industry-standard RS-485 differential bus transceiver in a DIP-8 package, functionally equivalent to the SP487EET and very cost-effective with broad availability.
  • ST485ECN --: Low-power RS-485/RS-422 transceiver with similar electrical characteristics and pinout, suitable as a second-source replacement for the SP487EET.
  • ADM487EARZ --: RS-485 transceiver with enhanced ESD protection and similar driver/receiver characteristics, suitable as a robust alternative when the original is unavailable.
