Electrical Characteristics

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.
