CD74HC688E Frequently Asked Questions (FAQs)

  • The CD74HC688E can handle clock frequencies up to 25 MHz.
  • The CD74HC688E requires a single 2V to 6V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply decoupling.
  • The propagation delay of the CD74HC688E is typically around 10ns to 15ns, depending on the operating voltage and temperature.
  • Yes, the CD74HC688E can operate at 3.3V, but the input and output voltage levels may need to be adjusted accordingly to ensure proper operation.
  • The enable inputs (E1 and E2) are active-low, meaning that they must be pulled low to enable the device. When E1 and E2 are both low, the device is enabled and the outputs are active. When either E1 or E2 is high, the device is disabled and the outputs are in a high-impedance state.
