These pins receive inputs for controlling the state of the outputs.
The input sections incorporate a PNP-type voltage comparator.
Non-connection
This pin connects to a DC motor. It has a current carrying capacity of 3 A in both sink and
source modes.
A diode for absorbing counter-electromotive force in the motor is incorporated on both V
ground sides.

GND terminal
Non-connection
This pin, along with pin 4, connects to a motor. It has the same function as pin 4. Its state is
controlled with inputs to pins 1 and 2.
Non-connection
Supply voltage terminal for motor drive
This is a supply voltage pin for the control section. It is completely separated from V
When this pin is open or connected to a ground, the current flowing through the motor is
minimized (100 µA).
