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.
