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 20., Table 21.

and Table 22.. Designers should check that the

operating conditions in their circuit match the oper-

ating conditions when relying on the quoted pa-

rameters.
