DESCRIPTION
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.

ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
affect reliability and cause permanent damage to the
device.
