5.1.3 AC/DC Characteristics
AC/DC characteristics involve the spread of values guaranteed within the spec-
ified voltage and ambient temperature range. Typical characteristics are the
median of the production. The device performance parameters marked with s
are not part of the production test, but verified by design or measured on an Infi-
neon evaluation board as desdribed in Section 5.2.
