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 0.1碌F 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

are 2-driver/2-receiver devices. This series is ideal for portable or hand-held applications such

as notebook or palmtop computers. The ESD tolerance of the

SP3222E/3232E

devices are

over

卤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 1碌A.
