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 characteristics Tables that

follow, are derived from tests performed under the Measurement Conditions summarized in

Table 7: Operating and ac measurement conditions. Designers should check that the

operating conditions in their circuit match the measurement conditions when relying on the

quoted parameters.
