Application Scenarios & Design Considerations

+5V-Powered, Multichannel RS-232 Drivers/Receivers

Alternative Part Number

  • ADM239AN --: Pin-compatible multi-channel RS-232 transceiver from a different series, widely used as a direct replacement for the MAX239 in DIP packages.
  • MC1489AN --: Classic quad line receiver in DIP, functionally similar interface role and easily sourced, though external charge pump may be needed for full RS-232 transmit.
  • ST232CN --: Low-cost 5V RS-232 transceiver with comparable driver/receiver count and DIP option, suitable as a functional substitute in many designs.
  • ICL239CPE --: Equivalent RS-232 driver/receiver in a DIP package with comparable electrical characteristics and pinout.
  • LT1139CN --: Similar 5V RS-232 transceiver offering comparable functionality and DIP package compatibility for drop-in replacement.
  • HIN239CP --: Equivalent 5V RS-232 transceiver with matching driver/receiver count and pinout, usable as a drop-in alternative.
