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. Pin 2 and Pin 8 are internally connected, and connecting both to GND
1
is
recommended.
3 V
IA
Logic Input A.
4 V
IB
Logic Input B.
5 V
OC
Logic Output C.
6 V
OD
Logic Output D.
7 CTRL
1
Default Output Control. Controls the logic state the outputs assume when the input power is off. V
OC
and V
OD
outputs are high when CTRL
1
is high or disconnected and V
DD2
is off. V
OC
and V
OD
outputs are low when CTRL

is low
and V
DD2
is off. When V
DD2
power is on, this pin has no effect.
