DESCRIPTION

The SP3223U and SP3243U 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 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/SP3243U 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 SP3243U 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 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.
