16. Application information

The slow input rise and fall times cause additional power dissipation, this can be

calculated using the following formula:

Padd = fi  (tr  ICC(AV) + tf  ICC(AV))  VCC where:

Padd = additional power dissipation (W);

fi = input frequency (MHz);

tr = input rise time (ns); 10 % to 90 %;

tf = input fall time (ns); 90 % to 10 %;

ICC(AV) = average additional supply current (A).

ICC(AV) differs with positive or negative input transitions, as shown in Figure 11 and

Figure 12.

An example of a relaxation circuit using the 74HC2G14-Q100; 74HCT2G14-Q100 is

shown in Figure 13.
