t_f = fall time (ns); 90 % to 10 %
I_CC(AV) = average additional supply current (A)
I_CC(AV) differs with positive or negative input transitions, as shown in Figure 14
and Figure 15.
74HC1G14 and 74HCT1G14 used in relaxation oscillator circuit, see Figure 16.
Remark: All values given are typical unless otherwise specified.
