Electrical Characteristics
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癈. Typical values represent the median values, which are
related to 25癈. If not otherwise stated, a supply voltage of V
CC
=15V is assumed for test condition
