Product data sheet
1. General description
The 74HC3G14; 74HCT3G14 is a high-speed Si-gate CMOS device.
The 74HC3G14; 74HCT3G14 provides three inverting buffers with Schmitt trigger inputs
which accept standard input signals. They are capable of transforming slowly changing
input signals into sharply defined, jitter-free output signals.

14. Application information
The slow input rise and fall times cause additional power dissipation, which can be
calculated using the following formula:
Padd = fi × (tr × ∆ICC(AV) + tf × ∆ICC(AV)) × VCC where:
Padd = additional power dissipation (µW);
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 (µA).
∆ICC(AV) differs with positive or negative input transitions, as shown in Figure 12 and
Figure 13.
An example of a relaxation circuit using the 74HC3G14/74HCT3G14 is shown
in Figure 14.
