DC and AC parameters
This section summarizes the operating and measurement conditions, as well as the dc and
ac characteristics of the device. The parameters in the following DC and AC Characteristic
tables are derived from tests performed under the measurement conditions listed in the
relevant tables. Designers should check that the operating conditions in their projects match
the measurement conditions when using the quoted parameters.
