Application Scenarios & Design Considerations

15KV ESD PROTECTED 5V RS-232 TRANSCEIVER

Alternative Part Number

  • MAX202ECWE+ --: Pin-compatible RS-232 transceiver in the same 16-pin SOIC wide package with equivalent +/-10V driver output and charge-pump design; widely available and a common drop-in replacement for the ST202E.
  • SP202ECN-L --: Direct functional equivalent RS-232 line driver/receiver with the same 5V supply, dual transmitters and receivers, and matching pinout; often used as a second-source part for ST202E.
  • ICL202ECWE --: Industry-standard RS-232 transceiver with identical function and pin configuration in 16-pin SOIC; a well-established alternate source when the ST part is unavailable.
