Product Highlight

  • Data Rate: 1000 kbps
  • ESD Voltage-Max: ±15 kV
  • Operating Temp Range: 0 to 70 °C
  • Supply Voltage: 3 to 5.5 V
EXAR, the market leader, offers the industry's broadest line-up of UART and serial protocol transceivers solutions.

With over 200 devices, wide 2.25 to 5.5V power supply range, 1 to 128 bytes of FIFO and compliance with the universal 3.3/5V PCI, Intel and Motorola bus interfaces, including single protocol ICs that support RS-232, RS-422 or RS-485 as well as dual and multi-protocol ICs that support from 2 to 8 of the most popular interface standards with a single IC, Exar has already done the difficult work for you.

We can deliver an immediate competitive advantage to your compressed time-to-market demands accelerating initial design, to functioning prototype and finally volume production.

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
The SP3232EU product family are a series of 3.3V, 1000 Kbps RS-232 Transceivers.
