Table 11. ADuM1310 Pin Function Descriptions
Pin No. Mnemonic Description
1
V
DD1
Supply Voltage for Isolator Side 1, 2.7 V to 5.5 V.
2 GND
1
Ground 1. Ground reference for Isolator Side 1.
3 V
IA
Logic Input A.
4 V
IB
Logic Input B.
5 V
IC
Logic Input C.
6 NC No Connection.
7
DISABLE
Input Disable. Disables the isolator inputs and halts the dc refresh circuits. Outputs take on the logic state
determined by CTRL
2
.
8 GND
1
Ground 1. Ground reference for Isolator Side 1.
9 GND
2
Ground 2. Ground reference for Isolator Side 2.
10 CTRL
2
Default Output Control. Controls the logic state the outputs take on when the input power is off. V
OA
, V
OB
, and
V
OC
outputs are high when CTRL
2
is high or disconnected and V
DD1
is off. V
OA
, V
OB
, and V
OC
outputs are low when
CTRL
2
is low and V
DD1
is off. When V
DD1
power is on, this pin has no effect.
11 NC No Connection.
12 V
OC
Logic Output C.
13 V
OB
Logic Output B.
14 V
OA
Logic Output A.
15 GND
2
Ground 2. Ground reference for Isolator Side 2.
16 V
DD2
Supply Voltage for Isolator Side 2, 2.7 V to 5.5 V.
