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

Table

10., 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.
