Application Scenarios & Design Considerations

True 3.0V to 5.5V RS-232 Transceivers

Alternative Part Number

  • MAX3232ECPE+ --: Pin-compatible RS-232 transceiver with the same 3.0V to 5.5V supply range and dual drivers/receivers, widely available and a direct functional drop-in for the SP3232E.
  • ST3232ECTR --: Equivalent 3V RS-232 transceiver in a similar 16-pin package with matching driver/receiver count and ESD performance, suitable as a lower-cost second source.
  • ICL3232ECAZ --: Industry-standard 3V RS-232 transceiver with the same pinout and functionality, offering a reliable alternative from a different series and manufacturer.
