Features & Applications
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 SP3220E devices are RS-232 driver/receiver solutions intended for portable or hand-held applications such as palmtop computers, instrumentation and consumer products.

These devices incorporate a high-efficiency charge-pump power supply that allows the SP3220E devices to deliver true RS-232 performance from a single power supply ranging from +3.0Vto +5.0V. This charge pump requires only 0.1μF capacitors in 3.3V operation.

The ESD tolerance of these devices is over ±15kV for both Human Model and IEC1000-4-2 Air discharge test methods. All devices have a low-power shutdown mode where the driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1μA.


  • Meets All EIA-232 and ITU V.28 Specifications from a wide +3.0V to +5.5V power supply
  • Interoperable with RS232 and V.28 at 2.7V
  • Supports High Serial Data Rates: 250 kbps SP3220E
  • 1μA Low Power Shutdown Mode
  • Footprint Compatible with MAX3221E, ISL3221
  • 4 x 0.1μF External Charge Pump Capacitors
  • Tri–State/Receiver Enable
  • Improved ESD Specifications:
    • ±15kV Human Body Model
    • ±15kV IEC1000-4-2 Air Discharge
    • ±8kV IEC1000-4-2 Contact Discharge
