Function
Power Supply Input. 5 V ± 10%.
Internally Generated Positive Supply (10 V nominal) on all parts, except ADM209 . The ADM209 requires an 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, and ADM213) External Capacitor (+ terminal) is connected to this pin.
(ADM206, ADM207, ADM208, ADM211, and ADM213) External Capacitor (– terminal) is connected to this pin.
(ADM206, ADM207, ADM208, ADM211, and ADM213) External Capacitor (+ terminal) is connected to this pin.
(ADM206, ADM207, ADM208, ADM211, and ADM213) External Capacitor (– terminal) is connected to this pin.
Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 kΩ pull-up resistor to V
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 kΩ pull-down resistor to GND is connected to each
input.
Receiver Outputs. These are TTL/CMOS levels.
Enable Input. Active low on ADM206, ADM209, 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.
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.
No Connect. No connections are required to this pin.
