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, ADM206, ADM211 and ADM213 feature a low power shutdown mode which reduces power dissipation to less than 5 W 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 is critical. The ADM213 has an active-low shutdown and an
