DESCRIPTION  
The DS229 is a triple RS-232 driver/receiver pair that generates RS-232 voltage levels from a single +5-  
volt power supply. Additional ±12-volt supplies are not needed since the DS229 uses on-board charge  
pumps to convert the +5-volt supply to ±10 volts. The DS229 is fully compliant with EIA RS-232E and  
V.28/V.24 standards. The DS229 contains three drivers and three receivers. Driver slew rates and data  
rates are guaranteed up to 116 kbits/sec. The DS229 operates with only 0.1 µF charge pump capacitors.  
OPERATION  
The diagram in Figure 1 shows the main elements of the DS229. The following paragraphs describe the  
function of each pin.
