Pin Function
Power supply pin for output and controller.
GND pins for output and controller. Both
must be grounded.
Input pins that determine the excitation of
the outputs.
IN1 control outputs OUT1 and OUT2; IN2
control outputs OUT3 and OUT4.
L: –0.3 to +0.7 V
H: 3.0 to 9.0 V
There are no limitations on the magnitude
relationships between the V
CC
and V
IN
supply voltages.

Output
Input pins that determine the constant-
voltage regulated output level.
The constant-voltage regulated output V
O
(= voltage between H side output and
GND) is controlled by V
