GENERAL DESCRIPTION  
The ADM202 is a 2-channel RS-232 line driver/receiver pair  
designed to operate from a single 5 V power supply. A highly  
efficient on-chip charge pump design permits RS-232 levels to  
be developed using charge pump capacitors as small as 0.1 µF.  
This converter generates 10 V RS-232 output levels.  
An epitaxial BiCMOS construction minimizes power consump-  
tion to 10 mW and guards against latch-up. Overvoltage  
protection is provided, allowing the receiver inputs to withstand  
continuous voltages in excess of 30 V. In addition, all pins  
contain ESD protection to levels greater than 2 kV.  
The ADM202 meets or exceeds the TIA/EIA-232-E and V. 28  
specifications. Fast driver slew rates permit 120 kB operation,  
and high drive currents allow extended cable lengths.  
The ADM202 is available in a 16-lead PDIP and both narrow  
and wide 16-lead SOIC packages.
