Application Scenarios & Design Considerations

+5V Powered Isolated RS-232 Drivers/Receivers

Alternative Part Number

  • LT1180ACSW --: Pin-compatible 5V RS-232 transceiver with internal charge pump, functionally equivalent to the MAX250 in most applications.
  • ADM202EARNZ --: Widely available dual-channel RS-232 transceiver with similar supply and interface characteristics, suitable drop-in replacement.
  • ICL232CPE --: Classic 5V dual RS-232 driver/receiver with on-chip charge pump, electrically similar and commonly used as a MAX250 substitute.
  • SP202ECN-L --: Low-cost RS-232 transceiver in the same SOIC package with similar driver/receiver configuration and supply requirements.
  • ICL202CPE --: Established RS-232 transceiver offering comparable performance and pinout, suitable as a drop-in replacement in most designs.
