DESCRIPTION

The SP3222U and the SP3232U 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 SP3222U and the 3232U

to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V.

The SP3222U 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.
