14-stage divider and oscillator Rev. 4 - 13 January 2022 Product data sheet 1. General description 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. The X1 input is overvoltage tolerant. This...
