Note:
4.3.1
Characteristics
The electrical characteristics involve the spread of values within the specified supply voltage and junction
temperature range T_J from – 40 °C to 125°C.Typical values represent the median values, which are
related to 25°C. If not otherwise stated, a supply voltage of V_CC =18V is assumed for test condition.
