Application Scenarios & Design Considerations

3-V TO 5.5-V MULTICHANNEL RS-232 COMPATIBLE LINE DRIVER/RECEIVER

Alternative Part Number

  • MAX3222ECPWR --: Pin-compatible 3V/5V RS-232 transceiver with dual charge pump, similar data rate and package, widely used as a direct TI SN75C3222 replacement.
  • SP3222ECY-L --: Equivalent 3V/5V RS-232 transceiver with 2 drivers and 2 receivers, same functional class and TSSOP package, good second-source option.
  • ICL3222ECAZ --: Industry-standard RS-232 transceiver with 2 drivers/2 receivers and integrated charge pump, functionally interchangeable with the SN75C3222 in most designs.
  • SP3222ECP --: Equivalent RS-232 transceiver offering the same driver/receiver count and shutdown function, suitable drop-in replacement for the SN75C3222.
  • ST3222ECDR --: Low-power RS-232 transceiver with matching pinout and functionality, providing a cost-effective alternative for the TI device.
