Application Scenarios & Design Considerations

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

Alternative Part Number

  • ADM239LJR --: Pin-compatible RS-232 transceiver from Analog Devices (which acquired Maxim), same 5V multi-channel driver/receiver function in a SOIC-wide package.
  • ST232ECWR --: Widely available 5V RS-232 transceiver with comparable driver/receiver count and ESD protection, suitable drop-in for many MAX239 applications.
  • ICL3232ECPZ --: Industry-standard 5V RS-232 transceiver with similar channel configuration and charge-pump design, good second-source option.
