DESCRIPTION
The SP3222B/3232B series is an RS-232 transceiver solution intended for portable or hand held applications such as notebook or palmtop computers. The SP3222B/3232B series has a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3222B/3232B series to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V.
