DESCRIPTION

The SP3220E device is an RS-232 driver/receiver solution intended for portable or hand-held

applications such as notebook or palmtop computers. The SP3220E device has a high-

efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation.

This charge pump allows the SP3220E device to deliver true RS-232 performance from a

single power supply ranging from +3.3V to +5.0V. The ESD tolerance of the SP3220E device

is over +15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods.

The SP3220E device has a low-power shutdown mode where the driver outputs and charge

pumps are disabled. During shutdown, the supply current falls to less than 1µA.
