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 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.

Table 4. Pin Function Descriptions
Mnemonic Function
VCC Power Supply Input. 5 V ± 10%.
V+ Internally Generated Positive Supply (10 V nominal).
V– Internally Generated Negative Supply (–10 V Nominal).
GND Ground Pin. Must be connected to 0 V.
C1+ External Capacitor (+ terminal) is connected to this pin.
C1– External Capacitor (– terminal) is connected to this pin.
C2+ External Capacitor (+ terminal) is connected to this pin.
C2– External Capacitor (– terminal) is connected to this pin.
TIN Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 kΩ pull-up resistor to VCC is connected to
each input.
TOUT Transmitter (Driver) Outputs. These are RS-232 levels (typically ± 10 V).
RIN Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is connected to each
input.
ROUT Receiver Outputs. These are TTL/CMOS levels.
EN/EN
Enable Input. Active low on ADM206 and 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 enabled. With EN = high (EN = low ADM213), the
outputs are placed in a high impedance state. This is useful for connecting to microprocessor systems.
SD/SD
Shutdown Input. Active high on ADM206 and ADM211. Active low on ADM213. With SD = high on the ADM206 and 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.
NC No Connect. No connections are required to this pin.
