CD4047BEE4 datasheet by Texas Instruments

CD4047BEE4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD4047BEE4?
  The recommended operating voltage range for the CD4047BEE4 is 3V to 15V.
• How do I ensure the oscillator circuit is stable and reliable?
  To ensure a stable and reliable oscillator circuit, use a high-quality quartz crystal, keep the crystal and capacitors close to the IC, and minimize stray capacitance and inductance.
• What is the purpose of the inhibit pin (INH) on the CD4047BEE4?
  The inhibit pin (INH) is used to disable the oscillator circuit when high, allowing the device to enter a low-power standby mode.
• Can I use the CD4047BEE4 as a voltage-controlled oscillator (VCO)?
  Yes, the CD4047BEE4 can be used as a VCO by applying a control voltage to the threshold pin (THRESHOLD) to vary the oscillator frequency.
• How do I choose the correct values for the external resistors and capacitors?
  Choose the external resistors and capacitors based on the desired oscillator frequency, crystal characteristics, and load capacitance. Consult the datasheet and application notes for guidance.
