CD4022BF3A datasheet by Texas Instruments

CD4022BF3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD4022BF3A?
  The recommended operating voltage range for the CD4022BF3A is 3V to 18V, with a typical operating voltage of 5V.
• How do I ensure proper power sequencing when using the CD4022BF3A?
  To ensure proper power sequencing, the VCC pin should be powered up before the clock input (CP) and the preset input (PR). Also, the VCC pin should be powered down after the clock input and preset input.
• What is the maximum clock frequency that the CD4022BF3A can handle?
  The maximum clock frequency that the CD4022BF3A can handle is 10 MHz, but this can vary depending on the operating voltage and load capacitance.
• How do I reset the counter to zero?
  To reset the counter to zero, the preset input (PR) should be pulled low for at least one clock cycle. This will reset the counter to zero and the output will be Q0 = Q1 = Q2 = Q3 = 0.
• What is the output current capability of the CD4022BF3A?
  The output current capability of the CD4022BF3A is typically 1.5 mA per output pin, but this can vary depending on the operating voltage and load conditions.
