SP3223

The SP3223 products are RS-232 transceiver solutions intended for portable applications

such as notebook and hand held computers. The SP3223 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 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 ideal for laptop/notebook computer and PDA applications.

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.
