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 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 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,
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.

*This is a stress rating only; functional operation of the device at these or any other
conditions above those indicated in the operation sections of this specification is
not implied. Exposure to absolute maximum rating conditions for extended
periods of time may affect reliability.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADM205–ADM211/ADM213 features proprietary ESD protection circuitry,
permanent damage may occur on devices subjected to high-energy electrostatic discharges.
Therefore, proper ESD precautions are recommended to avoid performance degradation or loss
of functionality.
