Product data sheet
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
14
74AHC1G4214 counts up to 2 = 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.

12.1 Typical crystal oscillator circuit
A typical crystal oscillator schematic is shown in Figure 8. R1 is the power limiting
resistor, its value depends on the frequency and required stability against changes in VCC
or average ICC. 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.
