DESCRIPTION  
The SP3281EB device is an RS-232 transceiver solution intended for portable or hand-held  
applications such as notebook and palmtop computers, PDAs, cell phones and their data cables  
and cradles.  
The SP3281EB is compatible with low voltage logic down to 1.8V using a logic select pin (VL)  
which conditions the logic inputs and outputs to be compatible with system logic.  
The SP3281EB 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  
SP3281EB device to deliver compliant RS-232 performance from a single +3.3V to +5.5Vpower  
supply and additionally adhere to EIA/TIA-562 driver outputs levels down to a power supply  
voltage of 2.35V.  
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.
