DESCRIPTION
The SP3223EU and 3243EU products are RS-232 transceiver solutions intended for portable or hand-
held applications such as notebook and palmtop computers. The "U" series is based on Sipex's
SP3223E/3243E series and has been enhanced for high speed. The data rate is improved to 1000kbps,
easily meeting the demands of high speed RS-232 applications. The SP3223EU and 3243EU use an
internal high-efficiency, charge-pump power supply that requires only 0.1碌F capacitors in 3.3V
operation. This charge pump and Sipex's driver architecture allow the SP3223EU/3243EU series to
deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The
SP3223EU is a 2-driver/2-receiver device, and the SP3243EU is a 3-driver/5-receiver device, ideal for
laptop/notebook computer and PDA applications. The SP3243EU 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
廬
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 1碌A.
