clock generator circuit

Circuit Notes:

  • Excellent clock generator to drive 4017 type CMOS circuits.
  • R1 = 10K to 10M, C1 = 100pF to 47uF.
  • Fo is ± 1KHz when R1 = 100K and C1 = 10nF.
  • You must use regulated 5V input voltage for 7400, while CMOS 4011 can be from 5 to 15V. Regulated power supply with LM7805 will be great to supply this circuit (with 7400).
