ADM205–ADM211/ADM213

PIN FUNCTION DESCRIPTION

Mnemonic

V_CC

Function

Power Supply Input 5 V ± 10% (+5 V ± 5% ADM205).

V+

Internally generated positive supply (+10 V nominal) on all parts except ADM209.

ADM209 requires external 9 V to 13.2 V supply.

V–

Internally generated negative supply (–10 V nominal).

GND

C+

Ground pin. Must be connected to 0 V.

(ADM209 only) External capacitor (+ terminal) is connected to this pin.

C–

(ADM209 only) External capacitor (– terminal) is connected to this pin.

T_IN

(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 kΩ pull-up resistor to Vcc is

connected on each input.

T_OUT

R_IN

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 con-

nected on each input.

R_OUT

Receiver Outputs. These are TTL/CMOS levels.

EN/EN

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.

SD/SD

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.
