Application Scenarios & Design Considerations

15KV ESD PROTECTED 5V RS-232 TRANSCEIVER

Alternative Part Number

  • MAX232ECPE --: Industry-standard RS-232 transceiver with the same 5V dual-driver/receiver function and pinout, widely available and directly interchangeable in most ST232E sockets.
  • ICL232CPE --: Pin-compatible 5V RS-232 dual transmitter/receiver with charge-pump design, offering equivalent electrical performance as a drop-in replacement.
  • SP232ECP --: Low-power 5V RS-232 transceiver with matching driver/receiver count and pinout, suitable as a functional substitute for the ST232E.
