The IC may be destroyed due to short-circuit between output pins, to supply, or to ground. Design an output line, V
and GND line with great care. Also, extremely high voltage will be applied to the IC when the IC is mounted in the wrong
orientation, which causes the IC to be destroyed. Always confirm the pin assignment and the position of pin 1 before mounting
and using the IC.

Make sure that GND wiring has only one contact point.
To input the data, see the section on the recommended input data.
If the signal setting is inappropriate, an unexpected large current may flow, causing damage to the IC.
