DESCRIPTION  
The SP3222E/SP3232E series is an RS-232 transceiver solution intended for portable or  
hand-held applications such as notebook or palmtop computers. The SP3222E/SP3232E  
series has a high-efficiency, charge-pump power supply that requires only 0.1µF capaci-  
tors in 3.3V operation. This charge pump allows the SP3222E/SP3232E series to deliver  
true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The  
SP3222E/SP3232E 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/SP3232Edevicesareover+/-15kVforbothHumanBodyModelandIEC61000-4-2  
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 1µA.
