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 ADM206,
ADM211, and ADM213 feature a low power shutdown mode
that reduces power dissipation to less than 5 µW, making them
ideally suited for battery-powered equipment. 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 that allow
operation from a single 5 V supply. These parts 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.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods of
time may affect device reliability.
ESD 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 this product 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.
