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 8., 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.
Table 8. Operating and AC Measurement Conditions
Note: 1. All voltages are referenced to VSS.
2. The Input Transition Time used in AC measurements is 5ns. For other input transition times, see Table 8.
