10-stage divider and oscillator
Rev. 3 — 11 January 2022
Product data sheet
1. General description
74AHC1G4210-Q100 is a 10-stage divider and oscillator. It consists of a chain of 10 flip-flops.
Each flip-flop divides the frequency of the previous flip-flop by two, consequently the
74AHC1G4210-Q100 counts up to 210 = 1024. 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
1024. 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 1) and is suitable for use in automotive applications.
