Product data sheet Rev. 04 — 5 May 2009 10 of 16 NXP Semiconductors 74AHC3G14; 74AHCT3G14 Inverting Schmitt trigger tf = input fall time (ns); 90 % to 10 %; ∆I CC(AV) = average additional supply current (µA). ∆I CC(AV) differs with positive or negative input transitions, as shown in Figure 15 and Figure 16. For 74AHC3G14 and 74AHCT3G14 used in relaxation oscillator circuit, see Figure 17. Note to the application information: 1. All values given are typical unless otherwise specified.
