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 ap-

plications. The SP3222EU/SP3232EU series has a high-efﬁciency, charge-pump power

supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the

SP3222EU/SP3232EU series todeliver trueRS-232 performance fromasingle powersupply

ranging from +3.0V to +5.5V. The ESD tolerance of the SP3222EU/SP3232EU devices are

over +/-15kV for both Human Body Model and IEC61000-4-2Air 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 1µA.
