PIN FUNCTION DESCRIPTIONS
Mnemonic
Function
Power Supply Input: +3.3 V
±
0.3 V.
Internally Generated Positive Supply
(+6 V Nominal).
Internally Generated Negative Supply
(–6 V Nominal).
Ground Pin. Must be connected to 0 V.
External Capacitor 1 is connected between these
pins. 0.1
μ
F capacitor is recommended but larger
capacitors up to 47
μ
F may be used.
External Capacitor 2 is connected between these
pins. 0.1
μ
F capacitor is recommended but larger
capacitors up to 47
μ
F may be used.
Transmitter (Driver) Inputs. These inputs accept
TTL/CMOS levels.
Transmitter (Driver) Outputs. These are RS-232
signal levels (typically
±
9 V).
Receiver Inputs. These inputs accept RS-232
signal levels. An internal 5 k
pull-down resistor
to GND is connected on each input.
Receiver Outputs. These are CMOS output logic
levels.
(ADM3222) Receiver Enable, Active Low. When
low, the receiver outputs are enabled. When high,
they are three-stated.
(ADM3222) Shutdown Control. Active Low.
When low, the charge pump is shut down and
the transmitter outputs are disabled.
(ADM1385) Shutdown Control. When low, the
charge pump is shut down and all transmitters
and receivers are disabled.
(ADM1385) Driver Disable. When low, the
charge pump is turned off and the transmitters
are disabled. The receivers remain active.
