HCF4047BEY datasheet by STMicroelectronics

HCF4047BEY Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the HCF4047BEY can handle?
  The HCF4047BEY can handle clock frequencies up to 10 MHz.
• How do I ensure that the HCF4047BEY is properly powered?
  The HCF4047BEY requires a single power supply voltage of 5V ± 10% with a maximum current consumption of 10mA. Ensure that the power supply is decoupled with a 100nF capacitor.
• What is the purpose of the MR (Master Reset) pin?
  The MR pin is an active-low input that resets the counter and the output stages when pulled low. It is used to reset the device to its initial state.
• How do I use the HCF4047BEY as a divide-by-N counter?
  To use the HCF4047BEY as a divide-by-N counter, connect the Q output to the CP (clock) input, and use the MR pin to reset the counter. The counter will then divide the input clock frequency by N, where N is the number of clock pulses required to reset the counter.
• What is the maximum output current that the HCF4047BEY can sink or source?
  The HCF4047BEY can sink or source up to 20mA of current per output pin.
