Application Scenarios & Design Considerations

ESD Protected to 15kV/ 5V/ Low Power/ High Speed or Slew Rate Limited/ RS-485/RS-422 Transceivers

Alternative Part Number

  • MAX485ESA+T --: Industry-standard half-duplex RS-485/RS-422 transceiver with the same 8-pin SOIC footprint and 5V supply, widely available and pin-compatible in most designs.
  • SN75176BDR --: Classic RS-485 differential bus transceiver in SOIC-8, functionally equivalent to the ISL8485E with similar data rate and drive capability.
  • SP485ECN-L --: Low-power RS-485/RS-422 transceiver in SOIC-8 with ESD protection, a direct functional substitute for the ISL8485EIB-T.
