CD74HCT688E Frequently Asked Questions (FAQs)

  • The CD74HCT688E can handle clock frequencies up to 40 MHz.
  • The CD74HCT688E requires a power supply voltage (VCC) of 4.5V to 5.5V, and it is recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply decoupling.
  • The CD74HCT688E can tolerate input voltages up to 7V, but it is recommended to keep the input voltage within the recommended operating range of 4.5V to 5.5V to ensure reliable operation.
  • The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (GND) and disabled when OE is high (VCC).
  • The propagation delay of the CD74HCT688E is typically around 10ns to 15ns, depending on the operating conditions and load capacitance.
