DESCRIPTION

The SP3222E/3232E series is an RS-232 transceiver solution intended for portable or hand-

held applications such as notebook or palmtop computers. The SP3222E/3232E series has

a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V

operation. This charge pump allows the SP3222E/3232E series to deliver true RS-232

performance from a single power supply ranging from +3.3V to +5.0V. The SP3222E/3232E

are2-driver/2-receiverdevices. Thisseriesisidealforportableorhand-heldapplicationssuch

as notebook or palmtop computers. The ESD tolerance of the SP3222E/3232E devices are

over ±15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods. The

SP3222E device has a low-power shutdown mode where the devices' driver outputs and

charge pumps are disabled. During shutdown, the supply current falls to less than 1µA.
