DESCRIPTION

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

0.1µFcapacitorsin3.3Voperation. ThischargepumpallowstheSP3222EUandthe3232EU

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.

The SP3222EU 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 1uA.
