GENERAL DESCRIPTION  
All members of the ADM230L family, except the ADM231L  
and the ADM239L, include two internal charge pump voltage  
converters that allow operation from a single 5 V supply. These  
converters convert the 5 V input power to the 10 V required  
for RS-232 output levels. The ADM231L and ADM239L are  
designed to operate from 5 V and 12 V supplies. An internal  
+12 V to –12 V charge pump voltage converter generates the  
–12 V supply.  
The ADM2xx family of line drivers/receivers is intended for all  
EIA-232-E and V.28 communications interfaces, especially in  
applications where 12 V is not available. The ADM223,  
ADM230L, ADM235L, ADM236L and ADM241L feature a  
low power shutdown mode that reduces power dissipation to  
less than 5 µW, making them ideally suited for battery powered  
equipment. Two receivers remain enabled during shutdown on  
the ADM223. The ADM233L and ADM235L do not require  
any external components and are particularly useful in applica-  
tions where printed circuit board space is critical.  
The ADM2xxL is an enhanced upgrade for the AD2xx family  
featuring lower power consumption, faster slew rate and opera-  
tion with smaller (1 µF) capacitors.
