74AHC1G4208 8-stage divider and oscillator Rev. 2 — 27 June 2019 Product data sheet 1. General description 74AHC1G4208 is a 8-stage divider and oscillator. It consists of a chain of 8 flip-flops. Each flip-flop divides the frequency of the previous flip-flop by two, consequently the 74AHC1G4208 counts up to 8 2 = 256. 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 256. The divider advances on the negativegoing 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. 2.

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 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. 74AHC1G4208 X1 1 Rbias = 560 kΩ 2 X2 VCC Rbias 100 kΩ to 1 MΩ R1 2.2 kΩ C1 22 pF to 37 pF 0.47 µF output 100 µF VI (f = 1 kHz) C2 100 pF A IO GND mna050 gfs = ΔIO / ΔVI at VO is constant.
