Function
Power Supply Input: +5 V
±
10%.
Internally Generated Positive Supply (+9 V nominal).
Internally Generated Negative Supply (–9 V nominal).
Ground Pin. Must Be Connected to 0 V.
External Capacitor 1 is connected between these pins. 0.1
µF
capacitor is recommended but larger capacitors up
to 47
µF
may be used.
External Capacitor 2 is connected between these pins. 0.1
µF
capacitor is recommended but larger capacitors up
to 47
µF
may be used.
Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 kΩ pull-up resistor to V
CC
is connected on each input.
Transmitter (Driver) Outputs. These are RS-232 signal levels (Typically
±
9 V).
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is
connected on each input.
Receiver Outputs. These are CMOS output logic levels.
Receiver Enable (Active High on ADM213E, Active Low on ADM211E); This input is used to enable/disable the
receiver outputs. With
EN
= Low ADM211E (EN = High ADM213E), the receiver outputs are enabled. With
EN
= High (EN = Low ADM213E), the receiver outputs are placed in a high impedance state.
Shutdown Control (Active Low on ADM213E, Active High on ADM211E); Refer to Table II. In shutdown the
charge pump is disabled, the transmitter outputs are turned off and all receiver outputs (ADM211E), receivers R1,
R2, R3 (ADM213E) are placed in a high impedance state. Receivers R4 and R5 on the ADM213E continue to
operate normally during shutdown. Power consumption in shutdown for all parts reduces to 5
µW.
