CD74HC125E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC125E?
  The maximum frequency of operation for the CD74HC125E is 40 MHz.
• Can I use the CD74HC125E in a 5V system?
  Yes, the CD74HC125E is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the enable pins (EN1 and EN2) in my design?
  The enable pins (EN1 and EN2) are active-low, meaning they need to be pulled low to enable the corresponding buffer. You can tie them to GND or use a logic signal to control them.
• What is the propagation delay of the CD74HC125E?
  The propagation delay of the CD74HC125E is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
• Can I use the CD74HC125E in a 3.3V system?
  Yes, the CD74HC125E is compatible with 3.3V systems, but you may need to adjust the input signal levels and ensure that the output voltage is within the recommended range.
