SN74HC74DRE4 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC74DRE4 is 25 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
  • The SN74HC74DRE4 requires a power supply voltage (VCC) of 2.0 V to 6.0 V, and it's recommended to use a decoupling capacitor of 0.1 μF to 1 μF between VCC and GND to ensure proper power supply decoupling.
  • The propagation delay of the SN74HC74DRE4 is typically around 10 ns to 15 ns, but it can vary depending on the operating conditions and the load capacitance.
  • Yes, the SN74HC74DRE4 can operate at 3.3 V, but it's recommended to check the datasheet for the specific voltage and current requirements to ensure compatibility.
  • The asynchronous reset input (CLR) should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) to ensure that the flip-flop is properly reset. A low signal on CLR will reset the flip-flop.
