Electrical Characteristics cont.

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

temperature range TJ from – 25°C to 125°C. Typical values represent the median values, which are related to 25°C. If not

otherwise stated, a supply voltage of VCC =15V is assumed for test condition.
