Characteristics
Note: The electrical characteristics involve the spread of values guaranteed 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 = 15 V is assumed.
