Application Scenarios & Design Considerations

Quad RS-485/RS-422 Line Drivers

Alternative Part Number

  • MAX487CPA --: Pin-compatible RS-485 transceiver with the same DIP-8 footprint and function; widely available and a common drop-in replacement for the SP487.
  • SN75176BP --: Industry-standard RS-485 differential bus transceiver in DIP-8, functionally equivalent and very easy to source.
  • LTC487CN --: Quad RS-485 driver in DIP package with comparable electrical characteristics, suitable as an alternative when the SP487 is unavailable.
  • DS3695N --: RS-485/RS-422 transceiver in DIP-8 with similar electrical characteristics, usable as an alternative when the primary options are unavailable.
