DC AND AC PARAMETERS

This section summarizes the operating measure-

ment conditions, and the DC and AC characteris-

tics 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 6, Operating and

AC Measurement Conditions. Designers should

check that the operating conditions in their circuit

match the operating conditions when relying on

the quoted parameters.
