74AHC1G4214 is a 14-stage divider and oscillator. It consists of a chain of 14 flip-flops. Each flip-flop divides the frequency of the previous flip-flop by two, consequently the 74AHC1G4214 counts up to 214= 16384. The single inverting stage (X1 to X2) functions as a crystal oscillator or an input buffer for an external oscillator. When used as a buffer the output X2 should be left floating. The frequency of the output (Q) is the frequency applied to X1 divided by 16384.The divider advances on the negative-going transition of X1.
