PULL-DOWN RESIST OR ON EACH RS-232 INPUT.  
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.  
Figure 1.  
All members of the ADM2xx family, except the ADM209,  
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 ꢀR-232 output levels.  
The ADM209 is designed to operate from 5 V and ±2 V supplies.  
An internal +±2 V to –±2 V charge pump voltage converter  
generates the –±2 V supply.
