Product data sheet
1. General description
74AHC1G14 and 74AHCT1G14 are high-speed Si-gate CMOS devices. They provide an inverting
buffer function with Schmitt trigger action. These devices are capable of transforming slowly
changing input signals into sharply defined, jitter-free output signals.
The AHC device has CMOS input switching levels and supply voltage range 2 V to 5.5 V.
The AHCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.

13. Application information
The slow input rise and fall times cause additional power dissipation, which can be calculated using
the following formula:
Padd = fi x (tr x ΔICC(AV) + tf x ΔICC(AV)) x 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 %;
ΔICC(AV) = average additional supply current (μA).
Average additional ICC differs with positive or negative input transitions, as shown in Fig. 14 and
Fig. 15.
For 74AHC1G14 and 74AHCT1G14 used in relaxation oscillator circuit, see Fig. 16.
