74AHC1G4212-Q100

12-stage divider and oscillator

Rev. 3 — 13 January 2022

Product data sheet

1. General description

74AHC1G4212-Q100 is a 12-stage divider and oscillator. It consists of a chain of 12 flip-flops.

Each flip-flop divides the frequency of the previous flip-flop by two, consequently the

74AHC1G4212-Q100 counts up to 2¹²= 4096. 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

4096. 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.

12. Crystal oscillator

12.1. Typical crystal oscillator circuit

A typical crystal oscillator schematic is shown in Fig. 8. R1 is the power limiting resistor, its value

depends on the frequency and required stability against changes in V_CCor average I_CC. For

starting and maintaining oscillation a minimum transconductance is necessary, so R1 should not be

too large. A practical value for R1 is 2.2 kΩ.
