CD4028BM Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD4028BM?
  The recommended operating voltage range for the CD4028BM is 3V to 18V, with a typical operating voltage of 5V.
• How do I ensure proper power sequencing when using the CD4028BM?
  To ensure proper power sequencing, apply power to the VCC pin before applying any input signals, and ensure that all input signals are at a valid logic level before applying power.
• What is the maximum clock frequency that the CD4028BM can handle?
  The maximum clock frequency that the CD4028BM can handle is 10 MHz, but this can vary depending on the specific application and operating conditions.
• How do I handle the asynchronous reset input (MR) on the CD4028BM?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor to ensure proper operation. A low signal on MR resets the counter to zero.
• Can I use the CD4028BM as a divide-by-N counter?
  Yes, the CD4028BM can be used as a divide-by-N counter by connecting the Q7 output to the CLK input and using the appropriate preset values.
