Intelligent +3.0V to +5.5V RS-232
The SP3223 and SP3243 products are RS-232 transceiver solutions intended for portable or
hand-held applications such as notebook and palmtop computers. The SP3223 and SP3243
use an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors
in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3223/
SP3243 series to deliver compliant RS-232 performance from a single power supply ranging
from +3.3V to +5.0V. The SP3223 is a 2-driver/2-receiver device, and the SP3243 is a
3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications.
The SP3243 includes one complementary receiver that remains alert to monitor an external
device's Ring Indicate signal while the device is shutdown.
The AUTO ON-LINE® feature allows the device to automatically "wake-up" during a shutdown
state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise,
the device automatically shuts itself down drawing less than 1µA.
