Mnemonic Function
V
CC
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.
T
IN
Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 kΩ pull-up resistor to V
CC
is connected to
each input.
T
OUT
Transmitter (Driver) Outputs. These are RS-232 levels (typically ± 10 V).
R
IN
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is connected to each
input.
R
OUT
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.
