DescriptionThe SP3223EU and 3243EU products are RS-232 transceiver solutions intended for portable or handheldapplications such as notebook and palmtop computers. The "U" series is based on Sipex'sSP3223E/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 aninternal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3Voperation. This charge pump and Sipex's driver architecture allow the SP3223EU/3243EU series todeliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. TheSP3223EU is a 2-driver/2-receiver device, and the SP3243EU is a 3-driver/5-receiver device, ideal forlaptop/notebook computer and PDA applications. The SP3243EU includes one complementaryreceiver that remains alert to monitor an external device's Ring Indicate signal while the device isshutdown.
The AUTO ON-LINE® feature allows SP3243EU to automatically "wake-up" during a shutdown statewhen an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the deviceautomatically shuts itself down drawing less than 1µA.
