74HC4024N datasheet by NXP Semiconductors

74HC4024N Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the 74HC4024N can handle?
  The maximum clock frequency of the 74HC4024N is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing characteristics in the datasheet for specific frequency limits.
• How do I ensure that the 74HC4024N is properly powered and decoupled?
  To ensure proper power and decoupling, connect the VCC pin to a stable 2.0-6.0 V power supply, and decouple the power supply lines with 100 nF capacitors as close to the device as possible. Additionally, use a 10 μF capacitor for bulk decoupling.
• What is the maximum output current that the 74HC4024N can sink or source?
  The 74HC4024N can sink or source up to 25 mA of current per output pin, but it's recommended to limit the output current to 10 mA or less to ensure reliable operation and prevent overheating.
• How do I handle the asynchronous reset input (MR) during power-up?
  During power-up, the asynchronous reset input (MR) should be held low for at least 10 ns to ensure that the device is properly reset. After power-up, the MR input can be released to allow normal operation.
• What is the recommended layout and routing for the 74HC4024N?
  To minimize signal integrity issues, it's recommended to use a symmetrical layout and routing for the clock and data signals. Keep the clock signal traces short and away from noisy signals, and use a ground plane to reduce electromagnetic interference (EMI).
