SN74HC74DR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC74DR is 25 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
  • To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF decoupling capacitor between VCC and GND, and use a 10uF bulk capacitor between VCC and GND. Also, ensure that the power supply is clean and free of noise.
  • The SN74HC74DR can sink or source up to 25mA of current per output pin, but it's recommended to limit the current to 10mA or less to ensure reliable operation.
  • The CLR input should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the flip-flop is properly reset. A low-going pulse on CLR will reset the flip-flop.
  • The propagation delay of the SN74HC74DR is typically around 10-15ns, but it can vary depending on the operating conditions and the quality of the clock signal.
