CD74HC423E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC423E?
  The CD74HC423E can operate at frequencies up to 40 MHz.
• How do I ensure that the CD74HC423E is properly powered?
  The CD74HC423E requires a single 2-V to 6-V power supply, and it's recommended to use a decoupling capacitor of 0.1 μF to 1 μF between VCC and GND to ensure proper operation.
• What is the propagation delay time for the CD74HC423E?
  The propagation delay time for the CD74HC423E is typically around 10 ns, but it can vary depending on the operating frequency and voltage.
• Can I use the CD74HC423E in a 3.3-V system?
  Yes, the CD74HC423E can operate at 3.3 V, but the output voltage will be limited to around 3.0 V. It's recommended to use a voltage regulator to ensure a stable 3.3-V supply.
• How do I handle the enable inputs (EN1 and EN2) for the CD74HC423E?
  The enable inputs (EN1 and EN2) are active-low, meaning that the device is enabled when the input is low. It's recommended to tie the enable inputs to GND or VCC depending on the desired operation.
