Single Schmitt-trigger inverter
15. Application information
The slow input rise and fall times cause additional power dissipation, this can be
calculated using the following formula:
P
add
=f
i
 (t
r
I
CC(AV)
+t
f
I
CC(AV)
)  V
CC
where:
P
add
= additional power dissipation (W);
f
i
= input frequency (MHz);
t
r
= input rise time (ns); 10 % to 90 %;
t
f
= input fall time (ns); 90 % to 10 %;
I
CC(AV)
= average additional supply current (A).
Average I
CC(AV)
differs with positive or negative input transitions, as shown in Figure 13.
An example of a relaxation circuit using the 74LVC1G14 is shown in Figure 14
.
Linear change of V
I
between 0.8 V to 2.0 V.
All values given are typical unless otherwise specified.
