DC and ac parameters
This section summarizes the operating and measurement conditions, and the dc and ac
characteristics of the device. The parameters in the dc and ac Characteristic tables that
follow are derived from tests performed under the Measurement Conditions summarized in
the relevant tables. Designers should check that the operating conditions in their circuit
match the measurement conditions when relying on the quoted parameters.
