Characteristics

4.3.1

Supply Section

Note:

The electrical characteristics involve the spread of values guaranteed within the specified supply voltage

and junction temperature range TJ from – 25

oC to 125oC. Typical values represent the median values,

which are related to 25°C. If not otherwise stated, a supply voltage of VCC = 15 V is assumed.
