DC AND AC PARAMETERS
This section summarizes the operating and mea-
surement conditions, and the DC and AC charac-
teristics of the device. The parameters in the DC
and AC characteristics Tables that follow, are de-
rived from tests performed under the Measure-
ment Conditions summarized in Table 9,
Operating and AC Measurement Conditions. De-
signers should check that the operating conditions
in their circuit match the measurement conditions
when relying on the quoted parameters.
