mentioned notes and the characteristics carefully. If you will modify and external circuit constant upon use, you should
allow for not only static characteristics but also transient characteristics, unexpected variation of external components
and our ICs.
Basic circuit function and operation can be guaranteed within the operating temperature range and within the operating
power supply voltage range. Upon use, check those ranges carefully and specify the content, element, voltage and
temperature.
