Application Scenarios & Design Considerations

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

Alternative Part Number

  • ADM202EARNZ --: Pin-compatible dual RS-232 transceiver in SOIC-16, direct functional replacement for MAX243 with similar driver/receiver count and supply requirements.
  • ST202ECDR --: Dual RS-232 driver/receiver in SOIC-16 with charge pump, functionally equivalent to MAX243 and widely available as a lower-cost alternative.
  • ICL202ECPZ --: Classic dual RS-232 transceiver with on-chip charge pump, same pinout family as MAX243, suitable drop-in replacement in most designs.
