DC and AC parameters
Note:
This section summarizes the operating and measurement conditions, as well as the DC and
AC characteristics of the device. The parameters in the following DC and AC characteristic
tables are derived from tests performed under the measurement conditions listed in Table 8:
Operating and AC measurement conditions. Designers should check that the operating
conditions in their projects match the measurement conditions when using the quoted
parameters.
