Table 4. Pin Function Descriptions
Mnemonic Function
V
CC
Power Supply Input 2.7 V to 3.6 V.
V+ Internally Generated Positive Supply, 7.25 V (6.5 V Nominal for ADM3310E, ADM3315E). Capacitor C4 is connected between
V
CC
and V+.
V− Internally Generated Positive Supply, −7.25 V (−6.5 V Nominal for ADM3310E, ADM3315E). Capacitor C5 is connected between
GND and V−.
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 1 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 1 µF
can be used.
C3+, C3− External Capacitor 3 is connected between these pins. A 0.1 µF capacitor is recommended, but larger capacitors up to 1 µF
can be used.
T
IN
Transmitter (Driver) Inputs. These inputs accept TTL/CMOS levels. An internal 400 kΩ pull-up resistor to V
CC
is connected on
each input.
T
OUT
Transmitter (Driver) Outputs. Typically ±5.5 V (±6.4 V for ADM3311E and ADM3312E).
R
IN
Receiver Inputs. These inputs accept RS-232 signal levels. An internal 5 kΩ pull-down resistor (22 kΩ for ADM3315E) to GND is
connected on each of these inputs.
R
OUT
Receiver Outputs. These are TTL/CMOS levels.
EN
Receiver Enable. A high level three-states all the receiver outputs.
SD Shutdown Control. A high level disables the charge pump and reduces the quiescent current to less than 1 µA. All
transmitters and most receivers are disabled. One receiver remains active in shutdown (two receivers are active in shutdown
for the ADM3310E).
For ADM3307E, R
OUT
3 is active in shutdown.
For ADM3310E, R
OUT
4 and R
OUT
5 are active in shutdown.
For ADM3311E, R
OUT
5 is active in shutdown.
For ADM3312E, R
OUT
3 is active in shutdown.
For ADM3315E, R
OUT
3 is active in shutdown.
NC No Connect.
