DESCRIPTION

The 74AHC1G/AHCT1G14 is a high-speed Si-gate CMOS

device.

The 74AHC1G/AHCT1G14 provides the inverting buffer

function with Schmitt-trigger action. These devices are

capable of transforming slowly changing input signals into

sharply defined, jitter-free output signals.

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW).

PD = CPD × VCC2 × fi + (CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in Volts.

2. The condition is VI = GND to VCC.
