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 W
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.
