4.Precautions in Application use
1.) This product is produced with strict quality control, but might be destroyed if used beyond its absolute maximum ratings including
the range of applied voltage or operation temperature. Failure status such as short-circuit mode or open mode can not be
estimated. If a special mode beyond the absolute maximum ratings is estimated, physical safety countermeasures like fuse
needs to be provided.
2.) The circuit functionality is guaranteed within of ambient temperature operation range as long as it is within recommended
operating range. The standard electrical characteristic values cannot be guaranteed at other voltages in the operating ranges,
however the variation will be small.
3.) When this product is installed on a printed circuit board, attention needs to be paid to the orientation and position of IC. Wrong
installation may cause damage to IC. Short circuit caused by problems like foreign particles entering between outputs or
between an output and power GND also may cause damage.
4.) The pin connected a connector need to connect to the resistor for electrical surge destruction.
