DC AND AC OPERATING AND MEASUREMENT CONDITIONS
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 Characteristic tables that follow are de-
rived from tests performed under the Measure-
Table 17. Operating Conditions
