Ground Pin. Must be connected to 0 V.
are disabled.
No Connect.
Power Supply Input (3.3 V ± 0.3 V).
Internally Generated Positive Supply (+6 V nominal).
Internally Generated Negative Supply (−6 V nominal).
External Capacitor 1 is connected between these pins. A 0.1 μF capacitor is recommended but larger capacitors up to 47 μF
can be used.
External Capacitor 2 is connected between these pins. A 0.1 μF capacitor is recommended but larger capacitors up to 47 μF
can 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 kΩ pull-down resistor to GND is connected on each input.
Receiver Outputs. These are CMOS output logic levels.
(ADM3222 only) Receiver Enable. Active low. When low, the receiver outputs are enabled. When high, they are three-stated.
(ADM3222 only) Shutdown Control. Active low. When low, the charge pump is shut down and the transmitter outputs
(ADM1385 only) Shutdown Control. When low, the charge pump is shut down and all transmitters and receivers are disabled.
(ADM1385 only) Driver Disable. When low, the charge pump is turned off and the transmitters are disabled. The receivers
remain active.
