CD74HC221M Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74HC221M is typically 10 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure proper power supply, connect VCC to a stable 2-6V power source, and GND to a reliable ground connection. Also, decouple the power supply with a 0.1uF capacitor to reduce noise and ensure stable operation.
  • The CD74HC221M can sink or source up to 25mA of current per output, but it's recommended to limit the current to 10mA or less to ensure reliable operation and prevent overheating.
  • The asynchronous reset input (MR) is active-low, so connect it to GND to reset the device. When MR is low, all outputs are reset to a low state. When MR is high, the device operates normally.
  • The propagation delay time for the CD74HC221M is typically around 10-15ns, but it can vary depending on the specific application and operating conditions.
