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.

ADM205–ADM211/ADM213
PIN FUNCTION DESCRIPTION
Function
Power Supply Input 5 V ± 10% (+5 V ± 5% ADM205).
Internally generated positive supply (+10 V nominal) on all parts except ADM209.
ADM209 requires external 9 V to 13.2 V supply.
Internally generated negative supply (–10 V nominal).
Ground pin. Must be connected to 0 V.
(ADM209 only) External capacitor (+ terminal) is connected to this pin.
(ADM209 only) External capacitor (– terminal) is connected to this pin.
(ADM206, ADM207, ADM208, ADM211, ADM213) External capacitor (+ terminal) is connected to this pin.
(ADM206, ADM207, ADM208, ADM211, ADM213) External capacitor (– terminal) is connected to this pin.
(ADM206, ADM207, ADM208, ADM211, ADM213) External capacitor (+ terminal) is connected to this pin.
(ADM206, ADM207, ADM208, ADM211, ADM213) External capacitor (– terminal) is connected to this pin.
Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 kpull-up resistor to Vcc is
connected on each input.
Transmitter (Driver) Outputs. These are RS-232 levels (typically ± 10 V).
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kpull-down resistor to GND is con-
nected on each input.
Receiver Outputs. These are TTL/CMOS levels.
Enable Input. Active low on ADM205, ADM206, ADM209, ADM211. Active high on ADM213. This input is
used to enable/disable the receiver outputs. With EN = Low (EN = High ADM213), the receiver outputs are en-
abled. With EN =High (EN = low ADM213), the outputs are placed in a high impedance state. This facility is
useful for connecting to microprocessor systems.
Shutdown Input. Active high on ADM205, ADM206, ADM211. Active low on ADM213. With SD = high on the
ADM205, ADM206, ADM211, the charge pump is disabled, the receiver outputs are placed in a high impedance
state and the driver outputs are turned off. With SD low on the ADM213, the charge pump is disabled, the driver
outputs are turned off and all receivers except R4 and R5 are placed in a high impedance state. In shutdown, the
power consumption reduces to 5 µW.
No Connect. No connections are required to this pin.
