DESCRIPTION  
The SP3249E device is an RS-232 transceiver solution intended for portable or hand-held  
applications such as notebook and palmtop computers. The SP3249E uses 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 SP3249E device to  
deliver compliant RS-232 performance from a single power supply ranging from +3.0V to  
+5.0V. The SP3249E is a 5-driver/3-receiver device, ideal for laptop/notebook computer and  
PDA applications.
