The SP3223E and 3243E products are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. The SP3223E and 3243E 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 SP3223E/ 3243E.
.3V to +5.0V. The SP3223E is a 2-driver/2-receiver device, and the SP3243E is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications. The SP3243E 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. SELECTION TABLE Device Power Supplies .
The SP3243E products (SP3243E, SP3243EB, SP3243EH, and SP3243EU) are 3 driver/5 receiver RS-232 transceiver solutions in.
