Features & Applications

The SP3222EU and the SP3232EU are 2 driver, 2 receiver RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or palmtop computers. Their data transmission rate of 1000 kbps meets the demands of high speed RS-232 applications. Both ICs have a high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump allows the SP3222EU and the SP3232EU to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. 

The ESD tolerance of the SP3222EU/3232EU devices are over ±15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods.


  • Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply
  • Interoperable with EIA/TIA - 232 and adheres to EIA/TIA - 562 down to a +2.7V power source
  • Enhanced ESD Specifications:
    • ±15kV Human Body Model
    • ±15kV IEC1000-4-2 Air Discharge
    • ±8kV IEC1000-4-2 Contact Discharge
  • 1000 kbps Minimum Transmission Rate
  • Ideal for Handheld, Battery Operated Applications
