The SP3223H and SP3243H products are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. The "H" series is based on Sipex's SP3223/3243 series and has been enhanced for high speed. The data rate is improved to 460Kbps, easily meeting the demands of high speed RS-232 applications. The SP3223H and 3243Huse an internal high-efficiency, charge-pump power supply that requires only 0.1F capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3223H/3243H series to deliver compliant RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The SP3223H is a 2-driver/2-receiver device, and the SP3243H is a 3-driver/5-receiver device, ideal for laptop/notebook computer and PDA applications. The SP3243H includes one complementary receiver that remains alert to monitor an external device's Ring Indicate signal while the device is shutdown.

The Auto-Online feature allows the device SP3243H 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 1A.
