SN74HC74DRG4 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC74DRG4 is 25 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
  • To ensure proper power supply, connect VCC to a 2.0-V to 6.0-V power supply, and GND to the system ground. Decouple the power supply with a 0.1-μF ceramic capacitor.
  • The preset (PRE) input is used to asynchronously set the Q output to a logic high level, regardless of the clock (CLK) input. This is useful for initializing the flip-flop or for resetting the output.
  • The asynchronous clear (CLR) input is used to reset the flip-flop. When CLR is low, the Q output is reset to a logic low level, regardless of the clock (CLK) input. Ensure that CLR is not asserted simultaneously with the clock edge to avoid metastability.
  • The propagation delay of the SN74HC74DRG4 is typically around 10-15 ns, but it can vary depending on the operating conditions and the load capacitance.
