CD4040BE datasheet by Texas Instruments

CD4040BE Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD4040BE can handle?
  The CD4040BE can handle clock frequencies up to 10 MHz, but it's recommended to operate it at frequencies below 5 MHz for reliable operation.
• How do I reset the CD4040BE?
  The CD4040BE has an asynchronous reset input (MR) that can be used to reset the counter. A low-going pulse on the MR input resets the counter to zero.
• Can I use the CD4040BE as a frequency divider?
  Yes, the CD4040BE can be used as a frequency divider. By connecting the Q output of one stage to the clock input of the next stage, you can create a frequency divider with a division ratio of 2^n, where n is the number of stages.
• What is the maximum output current that the CD4040BE can sink or source?
  The CD4040BE can sink or source up to 1.5 mA of current per output pin.
• Is the CD4040BE suitable for use in high-temperature environments?
  The CD4040BE is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to use it in environments with temperatures below 85°C for reliable operation.
