DESCRIPTION  
TheSP3220EdevicesareRS-232driver/receiversolutionsintendedforportableorhand-held  
applications such as palmtop computers, instrumentation and consumer products. These  
devices incorporate a high-efficiency, charge-pump power supply that allows the SP3220E  
devices to deliver true RS-232 performance from a single power supply ranging from +3.0V  
to +5.0V. This charge pump requires only 0.1µF capacitors in 3.3V operation. The ESD toler-  
ance of the these devices are over +/-15kV for both Human Body Model and IEC61000-4-2  
Air discharge test methods. All devices have a low-power shutdown mode where the driver  
outputs and charge pumps are disabled. During shutdown, the supply current falls to less  
than 1µA.
