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
12., Operating and AC Measurement Conditions
.
Designers should check that the operating condi-
tions in their circuit match the measurement condi-
tions when relying on the quoted parameters.
