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 Characteristic tables that follow

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

relevant tables. Designers should check that the operating conditions in their circuit match the

measurement conditions when relying on the quoted parameters.
