DESCRIPTION
The SP3223E and 3243E products are RS-232 transceiver solutions intended for portable or
hand-held applications such as notebook and palmtop computers. The SP3223E and 3243E
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 SP3223E/
3243E series to deliver compliant RS-232 performance from a single power supply ranging
from +3.3V to +5.0V. The SP3223E is a 2-driver/2-receiver device, and the SP3243E is a
3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications.
The SP3243E 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
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.
