Description : +3.0V to +5.5V RS-232 Driver/Receiver Pair

DESCRIPTION
The SP3220 device is an RS-232 Driver/Receiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The SP3220 device has a highefficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3220 device to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V.
The SP3220 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.
