CD74HC74E Frequently Asked Questions (FAQs)

  • The CD74HC74E can handle clock frequencies up to 25 MHz.
  • To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to VCC or GND, and use a pull-up or pull-down resistor to prevent floating inputs.
  • The recommended operating voltage range for the CD74HC74E is 2V to 6V, with a typical operating voltage of 5V.
  • Yes, the CD74HC74E can operate at 3.3V, but the output voltage levels may not be compatible with 3.3V logic. Ensure that the output voltage levels are compatible with your system's requirements.
  • The preset and clear inputs are asynchronous, meaning they can be asserted at any time, including during clock transitions. Ensure that these inputs are synchronized with the clock signal to avoid metastability issues.
