4.3 Characteristics
Note: 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
=15V is assumed for test condition.
