. And use power supply always at on state. Otherwise it will cause malfunction.
2. On driver gain setting of driver block.

6. Take time to check the characteristics on use.
When changing an external circuit constant for use, consider not only static characteristics, but also transient charac-
teristics and external parts with respect to the characteristics difference among ICs so that you can get enough margin.
7. Avoid short-circuit between output pin and power supply, output pin and GND (line-to-supply and line-to-ground
fault) and output pins (load short-circuit). Otherwise the IC will be damaged and is likely to get fired.
8. Be cautious on a dip soldering. Prior study is required.
