■ Enhanced ESD Specifications:
The SP3222EB/SP3232EB series is an RS-232 transceiver solution intended for portable or
hand-held applications such as notebook or palmtop computers. The SP3222EB/SP3232EB
series has a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors
in 3.3V operation. This charge pump allows the SP3222EB/SP3232EB series to deliver
true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The
SP3222EB/SP3232EB 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
SP3222EB/SP3232EB devices are over +/-15kV for both Human Body Model and IEC1000-
4-2 Air discharge test methods. The SP3222EB 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.
