Electrical Characteristics
5.1.3 AC/DC Characteristics
AC/DC characteristics involve the spread of values guaranteed within the specified voltage and ambient
temperature range. Typical characteristics are the median of the production. The device performance parameters
marked with ■ are not subject to production test. They were verified by design/characterization.
