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 ADM223,
ADM230L, ADM235L, ADM236L and ADM241L feature a
low power shutdown mode that reduces power dissipation to
less than 5 µW, making them ideally suited for battery powered
equipment. Two receivers remain enabled during shutdown on
the ADM223. The ADM233L and ADM235L do not require
any external components and are particularly useful in applica-
tions where printed circuit board space is critical.
All members of the ADM230L family, except the ADM231L
and the ADM239L, include two internal charge pump voltage
converters that 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 ADM231L and ADM239L are
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.
The ADM2xxL is an enhanced upgrade for the AD2xx family
featuring lower power consumption, faster slew rate and opera-
tion with smaller (1 µF) capacitors.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADM223/ADM230L–ADM241L 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.
