SN74HC74NE4 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC74NE4 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 with a minimum of 10uF decoupling capacitor between VCC and GND, and place the capacitor as close to the device as possible.
  • For optimal performance, use a symmetrical layout with the clock input and output traces as short as possible, and avoid running clock traces near noisy signals or under the device.
  • The CLR input should be asserted low to reset the flip-flop, and then de-asserted high to allow normal operation. Avoid asserting CLR during clock transitions to prevent metastability.
  • The maximum input voltage that the SN74HC74NE4 can tolerate is 6.5V, but it's recommended to keep input voltages within the specified operating range of 4.5V to 5.5V for reliable operation.
