CD74HC245M datasheet by Texas Instruments

CD74HC245M Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC245M?
  The maximum frequency of operation for the CD74HC245M is 50 MHz.
• Can I use the CD74HC245M in a 5V system?
  Yes, the CD74HC245M 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 (1E and 2E) in my design?
  The enable pins (1E and 2E) are active-low, meaning they need to be pulled low to enable the corresponding bus. You can tie them to GND or use a logic signal to control them.
• What is the propagation delay of the CD74HC245M?
  The propagation delay of the CD74HC245M is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
• Can I use the CD74HC245M as a level shifter?
  Yes, the CD74HC245M can be used as a level shifter, but it's not recommended as it's not designed for that purpose. Instead, use a dedicated level shifter IC for better performance and reliability.
