PRECAUTIONS FOR USING
This circuit does not integrate protection circuits such as over-current and overvoltage protectors.
Thus, the IC may be damaged if excess current or voltage is occurred to the IC. Make sure the IC design is fine
so that excess current or voltage will not be applied to the IC.
You must take extreme care to the design of the output line, VCC and GND line because IC may be destroyed
under the condition of short-circuit between outputs, air contamination fault, or fault by improper grounding.
