SP3243 General Description

The SP3223 and SP3243 products are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. The SP3223 and SP3243 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 SP3223/SP3243 series to deliver compliant RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The SP3223 is a 2-driver/2-receiver device, and the SP3243 is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications.The SP3243 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.
