RS Package Pin Configuration Table 3. Pin Function Descriptions Mnemonic Description VCC Power Supply Input (3.3 V ± 0.3 V). V+ Internally Generated Positive Supply (+6 V nominal). V– Internally Generated Negative Supply (−6 V nominal). GND Ground Pin. Must be connected to 0 V. C1+, C1– 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. C2+, C2– 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. TxIN Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. TxOUT Transmitter (Driver) Outputs. These are RS-232 signal levels (typically ±9 V). RxIN Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor to GND is connected on each input. RxOUT Receiver Outputs. These are CMOS output logic levels. EN (ADM3222 only) Receiver Enable. Active low. When low, the receiver outputs are enabled. When high, they are three-stated. SD (ADM3222 only) Shutdown Control. Active low. When low, the charge pump is shut down and the transmitter outputs are disabled. SD (ADM1385 only) Shutdown Control. When low, the charge pump is shut down and all transmitters and receivers are disabled. DD (ADM1385 only) Driver Disable. When low, the charge pump is turned off and the transmitters are disabled. The receivers remain active. NC No Connect. |
