APPLICATION INFORMATION
The slow input rise and fall times cause additional power
dissipation, this can be calculated using the following
formula:
P
Average I
transitions, as shown in Figs 14 and 15.
For AHC1G/AHCT1G14 used in relaxation oscillator
circuit, see Fig.16.
Note to the application information:
