Box 9106, Norwood, MA 02062-9106, U.S.A. Tel: 617/329-4700 Fax: 617/326-8703 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 ±12 V is not available. The ADM205, ADM206, ADM211 and ADM213 feature a low power shut- down 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 par- ticularly useful in applications where printed circuit board space is 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, in- clude 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 volt- age converter generates the –12 V supply. Table I.
