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 ADM205, ADM211 and ADM213 feature a low power shutdown mode which reduces power dissipation to less than 5 µW making them ideally suited for battery powered equipment. The ADM205 does not require any external components and is particularly useful in applications where printed circuit board space critical. The ADM213 has an active-low shutdown and an active-high receiver enable control. Two receivers of the ADM213 remain active during shutdown. This feature is useful for ring indicator monitoring. All members of the ADM2xx family, except the ADM209, include two internal charge pump voltage converters which 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 ADM209 is 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.
