PRECAUTIONS FOR USING
This IC does not include built-in protection circuits for excess current or overvoltage. If this IC is subjected to
excess current or overvoltage, it may be destroyed. Hence, the utmost care must be taken when systems which
incorporate this IC are designed. Utmost care is necessary in the design of the output line, COMMON and GND line
since IC may be destroyed due to short-circuit between outputs, air contamination fault, or fault by improper
grounding.
