DESCRIPTION
The SP3222B/3232B series is an RS-232 transceiver solution intended for portable or hand-
held applications such as notebook or palmtop computers. The SP3222B/3232B series has
a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V
operation. This charge pump allows the SP3222B/3232B series to deliver true RS-232
performance from a single power supply ranging from +3.0V to +5.5V. The ESD tolerance
of the SP3222B/3232B devices are over
±15kV
for both Human Body Model and IEC1000-
4-2 Air discharge test methods. The SP3222B 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.
