74AHC1G4214
14-stage divider and oscillator
Rev. 3 — 26 April 2018 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 2
14
= 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 feature allows the use of this device as a
voltage level translator in mixed voltage environments.
