GENERAL DESCRIPTION  
The ADM2xx family of line drivers/receivers is intended for all  
EIA-232-E and V.28 communications interfaces, especially in  
applications where ±±2 V is not available. The ADM206,  
ADM2±±, and ADM2±3 feature a low power shutdown mode  
that reduces power dissipation to less than 5 μW, making them  
ideally suited for battery-powered equipment. The ADM2±3 has  
an active low shutdown and an active high receiver-enable  
control. Two receivers of the ADM2±3 remain active during  
shutdown. This feature is useful for ring indicator monitoring.  
All members of the ADM2xx family include two internal charge  
pump voltage converters that allow operation from a single 5 V  
supply. These parts convert the 5 V input power to the ±±0 V  
required for RS-232 output levels.
