CD74HC4020M datasheet by Texas Instruments

CD74HC4020M Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HC4020M can handle?
  The CD74HC4020M can handle clock frequencies up to 25 MHz.
• How do I ensure that the CD74HC4020M is properly powered?
  The CD74HC4020M requires a single power supply voltage of 2V to 6V, with a recommended operating voltage of 5V. Ensure that the power supply is clean and regulated to prevent noise and voltage drops.
• What is the maximum input voltage that the CD74HC4020M can tolerate?
  The CD74HC4020M can tolerate input voltages up to 7V, but it is recommended to keep the input voltage within the recommended operating voltage range of 2V to 6V to ensure reliable operation.
• How do I handle the asynchronous reset input (MR) of the CD74HC4020M?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (typically 1kΩ to 10kΩ) to ensure that the device is properly reset. A low signal on the MR input will reset the device.
• What is the propagation delay of the CD74HC4020M?
  The propagation delay of the CD74HC4020M is typically around 10ns to 20ns, depending on the operating voltage and temperature.
