3. The current consumption values include input leakage current.
4. Maximum values are characterized values and not test limits in production.
29.3 Speed Grades
Maximum frequency is dependent on V
CC.
As shown in Figure 29-1 and Figure 29-2, the Maxi-
mum Frequency vs. V
CC
curve is linear between 1.8V < V
CC
< 2.7V and between 2.7V < V
CC
<
4.5V.
