Note:
Supply Section
The electrical characteristics involve the spread of values within the specified supply voltage and junction
temperature range T_J 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 V_CC = 18 V is assumed.
