IC Usage Notes
Maximum ratings
If the IC is used in the vicinity of the maximum ratings, even a slight variation in conditions may cause the maximum ratings to
be exceeded, thereby leading to a breakdown.
Printed circuit board
When drawing the printed circuit pattern, refer to the sample printed circuit pattern. Be careful not to form a feedback loop
between input and output.
