The SP3223U and SP3243U products are RS-232 transceiver solutions intended for portable or handheld applications such as notebook and palmtop computers. The "U" series is based on Sipex's SP3223/ SP3243 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 SP3223U and SP3243U 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 SP3223U/SP3243 U series to deliver compliant RS- 232 performance from a single power supply ranging from +3.0V to +5.5V. The SP3223U is a 2-driver/ 2-receiver device, and the SP3243 U is a 3-driver/5-receiver device, ideal for laptop/notebook computer and PDA applications. The SP3243U 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 SP3243U 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.
